Never mind. I contacted the vendor i bought the kit from and got my answer. So i just want to say thank you for all the advise. It helped me out tremendously.
I have a turbocharged 01 impala with the 3.8 and many mods ( I believe list of mods are in signature below). I have a extra pcm from an 00 grand prix gtp and was wondering if i could use it. My pcm...
After adding and subtracting anywhere from 0.50 - 0.01 g/s manually from the maf curve in open loop ( seeing my commanded afr changes while driving even though its set at 14,7 adders and the...
Just for S**ts & Giggles i took the original tune and just bumped the operating temp RPMs up to 950, and wrote it to the ECU. She fired up, but was idling @ 16.5 AFR. That was intriguing.
Yes i did that, and the problems still exists.
I followed Idle Rinkrats Tuning guide to get my car to start and adjusted the maf airflow in the idle areas. I am currently working on the Open Loop tuning using Russ k write up. And im running into...
I couldn't figure it out. Even After reading through multiple threads on a few sites. Its leaving me with more questions then answers. So I decided, Im going to start fresh. I made the following...
for some reason when i start my car the scanner will read its got 14-15 degrees of knock while idling and is readiing -5 degrees in timing. And when i blip the throttle wit goes away, and everything...
Got it, Thanks.
Sorry took so long to respond. Engine was leaking oil and coolant. Had to track that down and fix it.
Cool thanks for the clarification. Ill zero out that table. Right now ive just been sitting in my driveway idle tuning in open loop. So far I got my WB fluctuating between the High 13s, & 14s,...
So same as before, just play with maf curve till AFR is 14.7 or within 5%. Ive researched alot on the lucas 42.5 injectors. Its really a toss up. I didnt mess with my IFR though, it was already set...
I did as said. And added to the maf. Now my Ltft is reading 0 in idle. my wb err is all over the place but my afr on my gauge is and in Hp tuners are reading the same thing 14 - 16 afr at idle. Tune...
Awesome. Ill do that. I was reseting fuel trims but not disabling the fuel trim learn. What about any afr tables, would i need to change any of them?
I believe the afr error is correct. I idont know if i typed the experssion formula in correctly or not. To shut off full trims you mean by resetting them? Closed loop wasnt enabled, to do that do i...
I did some maf adjusting to the tune with the log in my last post. I also did a log after writing the changes to the pcm. Any insight would be greatly appreciated. I attached the tune with the maf...
After more researching and using lot of different word play in google, I came across a thread for the AEM WB ( 30-0300) EGR Formula for the standard interface on an l67.

I am still trying to get this math equation correct for the egr to jive with WB. I took a vid with the wb and scanner while logging for an idle tune, so I could pause the video and see how much it...
Any equation need like with the egr?
Edit ****
I found this video tutorial
https://youtu.be/Ru_2M2uGSKs
Is there a write up on it?
The video above works on the 3800. I was able to get my AEM uego 30-0300 wb to log in vcm scanner through the Egr signal wire. I just have to play with a number in the equation to get it to read...
I found a how to on youtube for the wb and erg for a 5.3 Silverado.
https://youtu.be/NDyiq3A5MIc
Would this work on the 3800 pcm?
After adding 1 gram to the maf curve in the 1500 - 3875hz section, 2 degrees of timing through the 0.08 - 0.28 grams and 400 - 1,200 rpm range in the hi octane table, the car is now able to start and...
I will give a try. Thanks
I set the idle to 950rpm. To adjust the maf curve i would goto maf calibration - Airflow vs. FREQ ? And to adjust the timing i goto Spark, Advanced and then Base Low Octane ?
Ive been researching and reading up on hp tuners for about a year now. Even when i didnt own hp tuners, i downloaded the software and some 3800 tunes, to look at while reading and watching videos....
