Thanks, decipha!

I failed to mention that I am doing all this without a wideband so the FE% is what TPRT is spitting out. I assume that is still OK.

The Flow values are only there because they are in the XL file I am using to do all the calculations. I'll be multiplying those by the FE% and setting it all up again.

I am (still) running through the first step to dial in fuel (looking at FE% at various IMAF points) and have made a couple of adjustments to the MAF curve. As this progresses, the KAMRF values are sometimes pegging at 0.969V. They regularly go above and below 0.969V but often = 0.969V for periods of a sometimes a few seconds or even much more. It seems that this is happening more as I adjust the MAF function but that could just be coincidence. I feel like I have reached the limits of the EEC to manage the short term fuel trims (i.e fuelling is way off) but there is one example where the FE% is being reported as around 0.98 at the same time as the pegging.

Also, in collecting FE% data, keeping IMAF constant for around 10s, the KAMRFs sometimes bounce between two (only two – nothing in between) values. In one log for example at 400 IMAF, the KAMRFs are either 0.988 or 0.992 (one or the other). At this time the FE% varies between about 0.98 and 1.02 and the LAMBSEs are around 0.98.

What does this all mean?

anything +-- 5% is dialed in, so any correction between 0.95 and 1.05 you ignore

Noticed recently that by IPSIBR value was high so made the necessary adjustments to the idle screw and now she idles warm at around the DSDRPM value and IPSIBR at 0.

Did a couple more IMAF runs and found something else.

On a couple of runs, while holding IMAF constant, HEGO2 drops and remains lean (around 0.03), while HEGO1 operates as normal, bouncing between 0.1 and 0.8.

I am running on one HEGO - #1 thankfully - but am wondering if this is a sign of an exhaust leak or something similar.

no way to know unless you know how lean it goes at that condition on the other bank

What I sometimes do is swap hego control to see the condition of the fuel overall by swapping all fuel control from bank1 to bank2

simply set numego back to 2 and change all of the injectors to use bank2 in the output port table

dont mind the CEL for hego1 setting a fault if it bothers you just disable the codes it throws for the o2 errors since that side isnt controlling anything lambses on that side bank1 can go all over the place since its not doing anything

anywho, with fuel dialed in first on bank1 after you swap to bank2 hego fuel control you can see what that side has to say

The way the PRO-M throttle linkages are, the only way I can undo the throttle stop lock nut is at WOT so I have to stop the engine to undo and retighten it. Unless I make a special spanner, which might be on the cards shortly.

So I have been loosening it off and then running the car at idle for a few minutes before adjusting the idle. Then I wait until the engine has cooled to save burning my fingers and then tighten the lock nut. Recently, when I tightened it, I am afraid I moved the stop screw slightly. I tried to return it to the same place but I suspect it isn't quite right. My idle RPM is good but the IPSIBR has lifted again.

Can I just do another regular idle reset (unplug IAC, TPS and SPOUT adjust and reconnect) or do I need to do something more (like battery disconnect).

fire it up get it up to warm operating temp and see what IPSIBR is at, if its at 0.05 or less then its fine, estimate 1/8th of a turn on the throttle stop for every 0.05 IPSIBR has to correct

Would there be any tell tales in a data log if there were a couple of pinholes in an exhaust?

Did some checking over the weekend and found two pinholes in the RH exhaust. One right at the head on #3 and the second just after the collector and just before the O2 sensor. Just wondering how much effect these might have on my data logs.

I will repair the exhaust but have to remove the engine to get the header off so looking at short term options. I am already just running with one HEGO (NUMEG0 = 1) so I will change this back to 2 and transfer the Injector Port Output from 111111 to 222222, ignore the CEL and see what happens (as per advice above).

So I managed to source the 8LD .bin file (thanks Pete) that has been running my engine via a J3 for some time. What I would like to do is load it up into TunerPro and QH and then run the car with it. I have it on a J3 but of course cannot data log or edit from there.

The 8LD runs a GUFA strategy as I understand it so I downloaded this form the TunerPro website and opened both in TPRT. Checking some basics suggests some definite mismatches. In fact, nothing looks any good at all. The .bin is a 56K file that would have originally been loaded to the J3 with Binary Editor.

So I tried the GUFx.xdf file that I have been using with the A9L2.bin just for laughs. The results were mixed. Some data appeared to be sensible - the MAF curve, the injector slopes. But there was some issues. The Injector Port Outputs were logical with 11112222. But NUMEGO was set at 102 - about 100 more HEGOs than I have or need. Obviously I will not attempt to run this on the engine.

Comparing the binaries suggests there was a bunch of data (about half maybe?) that was very similar but after a point, it diverged.

So... any ideas how I might run the 8LD.bin I have?

Thanks again decipha.

Unfortunately, no dice I'm afriad.

The GUF1 strategy produced similar results to the GUFA.

Since I am clutching at straws, I tried GUFB as well. Results were similar to GUFx. MAF, Injector Slopes, Firing Order, Injector Output Ports look good. Number of HEGOs and Number of Cylinders are definitely wrong (600 cylinders!).

Any other ideas?

Thanks again. That makes sense.

So any idea why the data is all over the shop when using this .bin and the GUFA.xdf file from the TunerPro website? The MAF Transfer is 30 points at 16V and 20763.71kg/hr. Number of Cylinders is 2047.

I tried the stock 8LD .bin and it was the same with the TP GUFA.xdf as well.

EDIT: I just checked the XDF Header Info and it suggests that is needs a 64K bin. I'll have a go at padding it out with null data. I remember reading something about how to do this somewhere on the homepage.

Done.

I added 8K of nulls to the .bin and now have 8 cylinders and sensible looking MAF Transfer. I reckon this should be good to go into the car, assuming it writes properly to the QH.

Will a 64K .bin work on the QH?

Alternatively, base offset of -2000 also works with the 56K .bin, displaying good data. Is this a better option?

I added the padding because the .xdf header states that it requires a 64K bin, with the first 8K being padded with null data.

In searching around the forum, I found a reference you made in this thread to adjusting the offset rather that padding the data: viewtopic.php?f=17&t=2686. Although this references issues with BE (with which I have no experience), I thought I would see if it helped.

So both methods appear to display appropriate data in TPRT.

The question is whether either is OK for the QH. I am guessing from your reply that the offset method is not appropriate.

as long as it views correctly u can write it no prob

I just dont see the point in using such an outdated strategy though. GUFA was iirc ~1986 where as gufb was 1987. I dont understand why anyone would want to use an outdated strat that has poor support when the much newer better supported strat is there for you.

Thats like going to a junkyard and grabbing a 500k mile engine out of a truck when right next to it theres an identical truck with only 100k miles. I don't see why anyone would do that.

This is mostly just a learning experience for me. I am not ignoring the incredible work that has gone into the A9L2 tune.

The 8LD .bin that is on hand has been running this car for a number of years. I am considering running it just to do some data logs to see where it has been sitting. It might be that I can pick up a few hints from the old tune. Hence why I have been keen to get a look at it.

Lots of people don't understand why I am messing around with 30 year old hardware. It puts my ECU alongside XTs and ATs and later the Intel 80386. Not many of those still hanging around.

In the end, it will be A9L2 on this ECU or a Haltech.

the problem is there is no support for that 8LD strategy since it was replaced by gufb and GUFX
I do not believe there is any datalogging support for it with tunerpro, if there is its got to be at least 10+ years old

there is literally 21 changes from a stock 8ld cal

here are those changes copied over to GUFX

Ah ha. Now I see. If I can't see data in TunerPro, then there is no real point in running it. I was really only interested in how the FE% was running at this stage - just to compare to where I am with the A9L2. It was also a bit iffy on a cold start and I was keen to look at what was happening there and see if adding some enrichment would have helped.

So, thanks for copying the changes over to GUFX. I'll give it a whirl just for laughs and then get back to the A9L2 tune.

Thank you for indulging me with getting the 8LD tune back into the car. I got it running but of course no data logging so not really much use. It does run pretty well so I had better get on with the A9L2 tune.

So I used the injector data from the reference page and have been fine tuning the (somewhat unknown) MAF Transfer (FN036).

Here is where I am at:
  • Holding throttle (free revving down low and driving up high) results in some good FE% values (mostly 0.98-1.02) for IMAF values from 200-600. KAMRFs are also steady at these times and close to 1.
  • I have done some half throttle runs from around 2000-6000rpm (IMAF 300-750) and the FE% bounces around close to 1 for the duration.
  • Idle has been adjusted and sits at 850-900 with IPSIBR at 0. I tried getting it a little lower (DSDRPM is 800) but the IPSIBR value will jump up quite quickly. It does drop but very slowly.
So I believe the next step is dialing in Spark.

I have read the Spark write up but I am still not sure exactly how to dial it in. I don’t have a dyno and the closest quarter mile is about 80 miles away.

Am I left with adjusting to as much spark as possible before it detonates and then adjust it back a little. This will be quite difficult for every load and RPM in FN2200. I am thinking a video camera of the dash while driving could help to note the load and rpm when detonation occurs. I have no roof though, so wind noise could be an issue!

Is there something that can be logged that will identify whether spark is close or not?

if u want to lower idle then lower nubase so ipsibr doesn't jump up to reach the higher rpm

no there is no way to know if spark is close or not other than adjusting it and seeing how the engine responds

Thanks once again - I'll head out to the *test track* and see how we go.

Been out and about checking and adjusting FN2200. Today I started out with the base A9L2+8 degrees (adv) I have been running for a while - as per the A9L2 write up. I was planning on making a few adjustments and testing as I go.

Starting from cold, I decided to make some startup adjustments just for laughs. I multiplied FN348 by 1.2 all round (it has been cranking a bit before firing) and multiplied all the 60 and 90*F cells (temp here is about 75*F) in FN1306/1361 by 1.4 as there has been some rough idle on startup.

Engine started quicker than it has done which I was happy about so I expect the PW change was for the better.

Drove the car (still cold) and was good for about 1/4 mile. It then popped and stumbled and stalled. Very unusual. Tried starting a few time and no go. I reverted to the previous tune which had been running quite fine and still no start. In desperation to avoid pushing it home, I uploaded the 8LD tune which the car has been running for years and kicked it over. With a little encouragement, it started and ran.

I drove (seemed perfect) about another 1/4 mile to turn around and the same thing happened suddenly. Pops and stumbles and stalled. Could not get it going on any tune that I had and towed it home.

Now it will simply not fire. FP runs for the decipha time (about 3s) on A9L2, cranks fine but no fire.

I pulled #1 plug and it looks a little dark. I am wondering if I added too much enrichment and have fouled the plugs completely.

I'll give it a go from cold tomorrow.

Any ideas as to what may be going on here?

mechanical issue

check the coil and fuel pump

first step is to replace the ecu relay and fuel pump relay

Cool, thanks.

Tried starting this morning and still nothing - not surprisingly.

Fuel pump runs as would be expected. About 3s on the A9L2 and about 1s on the old 8LD (mostly stock) tune.

I can't raise a spark by earthing the #1 lead so figure the coil might be cooked. Just to confirm, I'll hook up the timing light to check for a signal while cranking. That should confirm it right?! Then a new coil it is.

A couple of relays sounds like some good maintenance as well!

Cheers

EDIT: Got no response from a timing light on #1 or #2. Primary coil measured 0.8Ohms and secondary 4.95kOhms. Seems within reason but still cannot raise evidence of spark.

Is it possible to check the signal to the coil?

Turned out to be the coil.

Given that the car has done less that a tank of fuel on the tune, seems like an awful coincidence. Is there anything in the tune that could encourage a coil to fail?
