Still having the same issue but I have not had any time to work on the issue.

Been very cold where I live and they salt the roads so project cars go away.

bump anyone?

Would you all agree that what I am seeing is not normal and needs further investigation?

I think I have another ECU that is already licensed that I can try. Just want to make sure...

Hey Everyone,

I originally posted this in the engine section and just realized that it probably should have been in the transmission section.

I have a P59 from a 2004 Silverado that I swapped...

Hey Everyone,

I have a P59 from a 2004 Silverado that I swapped into a 1965 Buick Special. Engine, trans, ECU, and harness all came from the donor vehicle.

I am having an issue where the...

Hey everyone,

I have a 2000 S10 that originally came with a 4cyl 2.2L engine. I have since swapped in a 2000 4.8L out of a GMC Sierra 1500. I have changed the VIN to match the original S10 but...

I drilled out the throttle body to 3/16 but ran out of time to actually test it. Going to try and get the IAC steps down in the 50-60 range tomorrow between rain storms and tending to the brisket I...

bump any ideas if I have gone too far and have another issue somewhere that I am over looking?

so I have increased the set screw a lot. voltage at idle is around 0.73v and it seems that when you write to the ECU it resets the TPS because it is at 0%.

It is still stalling in gear.

Does...

I ended up not using the file from Jason as I had issues with it as well. I am not sure if he was scalling and what his fuel system is.

I will tell you don't expect the tunes from denmah to work...

Thank you for the replies everyone.

Camshaft specs are 228/230 .585/.585 on 112LSA and it has 7* of overlap.

I will increase the throttle stop screw to get the IAC position down lower and see...

I just read through the idle airflow section of the help site again. Seems that Base Running Airflow, Throttle cracker, and throttle follower are the main items that can affect IAC position in gear...

haha I was reading your post yesterday actually. Mine is a little different because I can see the gear indicator changing and the airflow changing between P/N and reverse or drive. Mine initially...

Everything I am seeing online and in the help section shows that only the base running airflow should be changing this value, not sure why it is doing what it is.

Also I noticed the airmass at idle is around 0.30 to 0.36. That seems high to me. Anyone else agree?

I have a problem where as soon as I put my car in gear, it runs like garbage and wideband shows 18+

I noticed that the IAC steps go from about 150 to almost 200.

The base running airflow is...

If someone comes across this post and has the same issue I found this document by looking through the help section (Who would have thought?)
...

I reset the idle airflow and realized I was about 6-7 grams over the factory values. I have reduced them so they are only 2grams above the factory values.

I will try these tomorrow and see if...

Hey everyone,

I have a 4.8L engine with a 228/230 112LSA .585/.585 camshaft. Also has deka 80lb injectors and 4l80e with a 3600 stall converter.

As soon as I put it into gear it dies.

Any...

I made some of those changes and it helped a lot.
I did the startup flare control table, flare control multiplier, stall saver, spark over and under speed.

I didn't touch the frictional airflow...

so I put the fuel settings back to factory for cranking and startup and it definitely is better. I am going to try and lean out even more to see if it continue to help.

I did start pulling some...

Hey everyone,

Can someone kick me in the right direction with this problem.

When I first start it up the rpm will overshoot then come down way too low, almost stall then back up and do that...

nvm I am an idiot.......

It down shifted from 3-2. Guess its time to drill out the holes in the plate for the larger converter. I can barely feel the shifts anymore.

Hey everyone.

I have a 2000 4.8L with a 78/75 turbo and a 4L80e transmission. The transmission has an HD2 shift kit and a recently installed (Used) Yank 3600 stall converter.

I noticed...
