Lots of changes and same problems hahah

[BKB]

Why do I always do this right before Carlisle Ford Nationals. Already registered and pretty much change every single thing about the car and expect things to just work.

When I swapped my 1994 3.8 V6 mustang computer out for the better supported J4J1 I didn't know I was going from OBDII back to the stone ages OBD1. I installed a switch on pin 46 & 48 so I can now sit and count the blinking light like its 1985.

511 Checksum
327 EVP/EPT circuit fault ( no EGR )
563 High Fan Fault ( The V6 uses only high speed fan. It is working and the connector and wiring is in great shape. Confused??? )
562 Aux fan circuit fail ( I don't understand this one )
558 EGR ( no EGR )

So that's it after checking several times, No cam sensor or sync codes.

I did run cam sensor wiring outside the car to see if this is a noise issue and still have the red sync in TunerPro. Also spun the cam sensor with a drill and read the wave form on the O-scope at the EEC connector and it looked identical as the bench test wave form. Also tried it 180' and just spinning it all over the place as the engine was running and never seen the sync change. Im very confident its timed properly using the tool and using my stock dampener to mark the BHJ dampener. 1 TDC on compression stroke the air stops blowing the second you hit the long mark on the BHJ that is TDC then spin CW another inch or so to the mark I made. Drop the cam sensor in and put the tool on with half moon facing the block. Engine has a new double roller T-chain so everything is tight.

If you still think I have a cam sync issue I did find a TSB that I belive gives me a visual on timing between PIP and Cam, Might need a real O-scope to get me enough screen to capture it all. That's about all I can think of.

Tip in is still rich. Need to get you a 0 vacuum 0 boost log since I have no fuel going into boost. Car is so much smoother, I guess this is a function of timing being under control during decel and low load. My driveshaft used to clank around and the exhaust would shake so violently it would hit the panhard bar. Thanks for everything I am learning a lot but still need to put a lot more time into all this.

Cam sync fault wont set any codes, only a hard cam sensor fault would throw a code.

I'll double check my logging code when I get a chance just to verify.

I don't see it tipping in rich I see decel going lean and closed loop dumping fuel then when you tip in its enriched. If your looking at the wideband it'll show a rich lambda but that's whats being commanded.

sealevel spark table wasn't being used for decel, i copied it over to altitude which was being used. Should have a ton more tq reserve on decel now.

i wrote some maf jitter backflow code so we can manually dial in decel fuel in fn1036. should be a significant improvement.

I kicked up the crank pw when cold firing off, if its harder to fire off hold the pedal to the floor to enable flood clear mode and shut off the injectors.

All looks good other than the fueling inconsistencies on decel, not much a problem though.

Load this in and shoot me back another step 1 log, if all goes well include a single wot pull from idle to shift rpm in 1st or 2nd. Watch the wideband and let me know what the gauge says while your on it. If it goes any leaner than .85 cut the pull short.

I will try and do TSB 02-22-1 and see if I can capture crank and cam signals to see if they are out of time. Also looking for a backup EEC just in case.

That was a pretty enjoyable drive, the DFSO right after I let of the throttle can be a bit violent if you're not shifting. I really don't have any fuel enrichment easing into the boost at least up to 5psi. I was seeing .83 - .86 at WOT. No co-pilot tonight.

I don't think your ecu is the problem, if need be I can snatch one out of my 94 5spd or 95 auto as a loaner no problem so I wouldn't worry about it , but it seems to be working fine.

It's far better to do it all in one larger log rather than splitting them up when ever you can. Especially with wot as the before and after are pretty critical.

Yeah i was purposely holding CL at 5psi at 2k rpm to verify the fueling, no biggie.

That DFSO you were feeling at 3k isn't dfso its transient fuel yanking everything out cuz load isn't decaying; my clip code is flipping load like a switch so transient fuel is flipping like a switch too.

The cold start log was blank, all the others were good though.

Your wideband doesn't read correctly at closed throttle. Not too uncommon with the innovates but definitely something you need to know.

She looks excellent. I posted a CZAW0 xdf in the supercoupes section. Go ahead and snatch it.
You shouldn't have any issues dialing her in as she's pretty much there.

enjoy

Using BE EA for over 15 years you get into the habit of making many short logs, or at least that's the way I used to do it.

This transient fueling that acts like a light switch with the throttle really shocks the drive line, can that be softened up somehow? Also can I use DFSO or will that defeat the transient fueling? Its a function I always really liked.

Car rips pretty good, working on some fueling going into boost. All those years of training the wife how to navigate BE and tune on the fly wasted. She is not a fan of tunerpro and I'm not in a position to teach.

I have decided I will be bringing the car to you once I install the MP blower case and weld up a inlet plenum. As of now that's planned for this winter so I will touch base once that's completed. Thanks for everything.

I just had total recall when you said that, I vividly recall back in the day how much of a PITA it was go through BE logs when you were looking for something specific and the biggest issue was that is exported all extrapolated data values in to plain text so the logs are pretty big file sizes and you can't easily manipulate the data or make changes to your wideband transfer etc... after the log was created. Pretty amazing what the mind chooses to forget lol.

Tunerpro is far superior as it streams the actual raw hex so logs are only a fraction of the size and there's no extrapolated values its just raw data. Its a major step forward (or backwards since tp preceded be) in terms of data acquisition.

Yeah tunerpro from BE takes a while to transition, took me a few years as I was very hesitant and fought it the entire way. I then realized I don't need no stinking tree view or anything as everything I do is by using control F and finding exactly what i need. In terms of time spent looking for something its not even close to anything else out there. The find box in tunerpro again is the gold standard that all other tuning software aspire to have.

What ever it is your looking for just hold control and press F to bring up the find box, type in what you want and then just double click it when it pops up in the search box to open it.

I disabled anticipation, anticipation was lagging big time when you got in the throttle below 1500. It took at least 4 background loops before it finally caught up. Dynamic make up fuel can't compensate because the sync flag isn't being set for sequential fire either which made it worse. Disabling aircharge anticipation makes it respond faster to larger transient corrections. You can see load was increasing slowly (at times .30) per loop instead of going straight to where it should have when IMAF didn't change throughout.

Because I disabled anticipation I had to enable idle aircharge smoothing, hopefully it doesn't cause idle to get to goofy and should maybe help stabilize idle more.

I disabled transient fuel on decel. I commanded enrichment on decel now too to help stabilize it, should take that nasty conk out when slapping the throttle shut. I added 1 second to the part throttle to idle spark decay delay as well for good measure.

I enabled DFSO for you.

Where is your ACT sensor located? It seems to be reading a tad lower than I'd expect it to.

One things for certain, many years ago using BE you'd never be able to get this level of intricate detail to see what exactly is going on. I'm willing to bet with this updated tune (if it goes as I expect) this is probably the best this vehicle has ever ran since '99 or whenever it was you did the swap or if transient is that far out to lunch now it'll probably run worse than the last revision.

Your transient fuel puddle on decel actually enlarges, very odd as I've never seen an SBF type engine ever do such a thing. In any case I kicked up the transient fuel down low which is higher than above it. This will cause tip in to lean out a touch. This is extremely evident numerous times through out when you tip in any load lags which would lean it but it actually enriches.

Your transient fuel is going to be all jacked up right now til we can see how she trends.

Also as for your fault code 562 for the auxiliary fan, I disabled it, I assume you didn't wire up the 3rd fan for the auxiliary fan the supercoupe has.

You can bring the car if you wish but its really not needed. Only thing a dyno is going to give you is just a rwhp number. By all means though your more than welcome to bring her down and we'll strap her and spin her up.

Your maf from 200 count on up looks to be dialed in perfectly. It's nice that she's consistent, within' 1% fuel error is pretty extraordinary.

I rewrote FN820b to be a part throttle/wot iscdc multiplier. I seen a couple times where you slipped the clutch without enough throttle input and the R's dropped below idle. This should help in those cases.

I kicked up the fuel pump prime time from 1 sec to 3 sec. See if it helps cranking fire off a touch faster.

post back another log to verify all is functioning correctly. Also, start recording the log before starting the engine and after you start recording press the throttle a few times rapidly so i can see if iscdc changes when you do.

Also you said previously your only using the high speed fan output... Can you verify what pin number your using for your fan relay when you get a chance? Does the fan come on when the ac is turned on?

That's a lot worse for sure, cold start was brutal. Probably died 7 times till it got warm and was able to take it for a short drive, got back and found it stopped logging at some point. Both computers do this from time to time.
It's been pretty cold in PA, 67 in the garage when I started it this morning and I was going to look back and see what the ACT was in the log but it didn't save it. ACT is in the return Plenum going into the lower intake. I will take note of the ACT,ECT and garage temp next time.
I have time today and have received my pile of spare parts from rockauto to look more into this cam sync issue.

The decel transient rpm scalar to omit didn't work. Its actually dumping fuel on decel now and the injectors are still leaning out.

It looks like something is going on with your injectors. At 230 (.5) to 232 (.5) engine run time (top right corner) you can clearly see it lean out 60% under exacting conditions. Do you have any other injectors you can toss in for testing? Doesn't matter the size just anything you know that's functional.

These must be really old injectors? what was the final price in the group buy ? which vendor was it? I've never seen a Siemens injector fluctuate before, any chance these are knock offs?

Any who attached with transients reverted. Should be better but definitely isn't going to be perfect.

Birdofprey97 ordered May 13 2011 $255 for 6. He was doing a lot of 60s and 80s group buys back then, you were active on the board then and commented on one of the group buys. he worked with multiple vendors so anything is possible.

(( The vendor I am going through has sold injectors to you in the past Dave at least that is what he stated last night. I know this vendor does over 8,000 injectors a month and has any other injector available but this one. I was told about them from my over seas friends that restore American cars and this vendor is here in the states. A quick call to Siemen backed up what has been stated. ))

I have a set of antique MSD50s, the original 3.8 14s, and I a set of red 42s I think. All would need to be sent through the injector cleaner do to sitting over a decade. That would have to wait till after Carlisle. I have the scope set up now capturing pip and cam and trying to confirm timing. I have been working on a few back up tunes just in case so I might need to start concentrating on those.

[BKB]

None of these sync? I think im right in the ball park but have no good data to go off of.
