Thanks for your efforts but something is off pretty bad. Check engine light is flickering and rpm is sporadic (1000-2000) and missing terribly. I tried to log it but nothing populated in the dash and it was so violent I just shut her down. I checked PIP Degrees is 120 but thinking something is still set up for a v8 somewhere.

no that means the ecu is resetting because its corrupt. i overwrote 1 byte on my custom code for the larger VE table.

here give this a try.

Hey that 1 byte was important :lol:

MAP is weird and is a pretty major performance/driveability regression but it works! I made it short cause running rich and have the nice sulfur smell from the cats. Not sure if the 02 is completely dead now or if it is OL due to MAP sensor reading off. Had a check engine light for bit before I started logging but it went off.

I got the new o2 installed today and started working on the new strategy. Making good progress but I am a bit confused about the new injector slope setup. I ended up changing the old value to get it running right. The new one did not seem to have an effect on lambse.

Getting great results with the new strategy. Thank you. FYI it does not seem to effect anything but MAP is still jumping all over the place. Also I am having trouble taming the idle now. Is there anything I should try before going through the mechanical idle setup? I noticed my throttle plates have a small hole drilled in them. Should I sorry about plugging them? Others have reported it helping. Idle cold seems fine after a minute or so but once she warms up I am at 1400-1500rpm.

Is this what you are referring to?
If using TunerPro RT, I have setup a histogram to dial in FN1036. Simply copy and paste that table into your tune along with the axis scaling.

no fn1036 is for inferred load

the VE table histograms is what you want, it gives you the correction value for each cell

open the histo and set it to running average thrn go for a short drive in varying conditions

apply the errors from the tablrme to the ve table and then repeat til all the errors are between 1 and 1.05

Got it, that's what I've been doing. It sounded like you were saying there was some automagical way for tuner pro to update the ve table with the histogram (feature request :D). Call me lazy but there are a lot of cells that need correction so I am just setting up an excel doc to make the adjustments in bulk. The histogram has rpm columns that aren't in the ve table so makes it a little more difficult.

This should help make it easier for others on A1C (easily adaptable for other strats). Three sheet excel doc for simple copy and paste from TunerPro RT to generate completely updated VE table in seconds. I checked for errors but please confirm this looks good to you.

I was having a hard time getting my tb set to idle and start good. got the QH going on the data, and first thing i adjusted was lowering SARCHG to 4.9 the map smoothed out, and i was able to set the TB correctly. bout to head out for a test.

***EDIT**** I left it at 400 CI and lowered SARCHG from 5.8 to 4.9 made a huge difference in start, idle, and drivability.

It appears changing the engine size has a direct impact on fuel calculations so I would image a change in the right direction would improve performance, idle and drivability. Decipha would need to clarify if it has any other implications.

following the cubic inch of 400 that calculates more to 6.6 liters not 5.8. so i started lowering that value, and am down to 4.3 now. best this truck has ever run. pretty amazing honestly. i can actually stay in OD now at 70 with a 2.73 final and pull a grade with out the need to down shift.

Glad to hear that worked well for you. I have been playing with engine size and once changing it I am having to dial in the VE table again. I don't know enough about other effects this might have to feel comfortable setting it arbitrarily. Performance on the stock inline 6 with 80lb injectors on e85 is definitely a major upgrade. Fuel economy is only down about 10% highway and 20% in the hills. I assume the advanced timing makes mpg better than the 30% loss I expected. Mechanical Idle settings have tamed light throttle drivability and make is a lot more predictable in low rpm pulls up the driveway.

Still fighting with the new A1C strategy in regards to OL commanded lambse being locked at 1. I tried setting the OL fuel to 0.8 across the board without any effect. I am staying out of WOT for now. The 80s @ 58 psi are have some dwell at low load but I have the fuel dialed in to the point where VE histogram stays mostly between .9 and 1.05. I am not sure if this can be improved without lowering fuel pressure. The only other issue is inconsistent ldle. Just waiting for FN800 to be added before I mess with it any more. Hoping to finish this baby up soon and post a good tune file.

new A1C is posted in downloads with FN800 added. FN800 cannot cause idle consistencies though.

FN820B needs to be set to all 1's otherwise you will have idle oscillations. That's most likely your idle issues.

OL should be at 1.000 lambse that's what I set them for with the base fuel table at all 1's. On speed density strats I use the WOT function FN303 to set the commanded lambse at WOT. You shouldn't be in open loop otherwise. Its most ideal to use throttle for enrichment on speed density since its much more consistent than map.

Thanks! I will start working with this tonight. I downloaded the new files. Just curious what the difference between A1C.bin and Z2D1.bin and which one I should use. Both are in A1C_56k.zip
Also should I disregard the x-axis weirdness in the screenshot?

The A1C is for a 6cyl.
The Z2D1 is for 8cyl 302ci.

I think the x-axis is missing some scaling in the XDF, or the extended VE patch isn't working right. I'm sure he'll fix that up.

I have a 8cyl 351w, just have to figure out all scalars I need to update, and will be trying out this tune as well.

neither is for a v6 they are borh 5.0s

dont use either why would you? continue with your existing tune.

for a 351 you simply change the engine size to 351.

Still fighting idle issues. I am having trouble interpreting all of the fn800 stuff. Setting throtlebody airmass appears to be the only way to tame it right now. any help with this would be appreciated.

Allow 0% ISCDC at 0 lbs/hr, remove clip of 10%, Clip max ISCDC to 98%, reduce 100% values


Here is what I have right now for FN800

Code: Select all
0.000   0.00
0.045   0.20

Finally got the idle tamed. Replaced faulty TPS and IAC and soldered the holes in the throttle blades. DSDRPM and N are still off by 1-200 rpm but ISCDTY is 40%. With mechanical Idle is it appropriate to increase Throttle body airmass to close IAC and reach desired RPM? Is there a better way? My set screw is almost completely out.

iscdc high means the theottle body needs to be opened to give it more air

no, the throttle body airmass must always be 0

I noticed PFEHP - EGR Type SW is set to 2 and the notes suggest this is not a good idea. I have it running almost perfectly except for surging/missing at very light light throttle. Any direction here would be appreciated.

Wow that smoothed it right out. Almost completely satisfied with this tune. Pulls like never before. :)
I do occasionally get a check engine light for a short period of time usually when cold. Is there a simple way to pull the codes in tunerpro or should I just get a ODB1 scanner?
