Hi All,
I am really battling with knock (L98- E38). I have calibrated my MAF and VE to around 1% accuracy on LTFT. My car was dyno'd for WOT –P.E. and my spark in the high 0.50 APCYL, is fine....

Hi All,
After many attempts to change the AFR from 14.63. I have come to terms with myself, (Ha ha) that it cannot be done in closed loop. I have fiddled with the PE and that seems to meet my needs....

Hi Simon,

Good idea. I have reset all my settings. My LTFT are back to +/-0.5%, so i am calibrated on MAF and VE.
I have set my pe to come in at 60kpa and throttle at 40%. My PE is starting at...

Hi All,
Thank you for your help. The answers is a bit disappointing. I was trying to richen up to 14.00. I feel the car does not like 14.63 on high altitudes and hot temperature. It feels better on...

Hi Gmh,

Thank you for your reply. So in a nutshell, what you are saying is that I can't change my AFR from 14.63 in closed loop.

Hi All,

I will follow up on those points.
The issue that is confusing me though, is why did the LTFT move by the same % I change the AFR in table (B3671). When I set table B3671 to 14.63 my LTFT...

Hi All,

Over the last view weeks/months I have been working with weatherman Shaun’s concepts on MAF and VE calibration and have been having some good success. However I made a change yesterday...

Hi Shawn,

Hi All,

Thank you for all the great reply's. I have been away for a few days and have only been back today. I tend to agree that the LC1 is most likely the problem. To my knowledge, our fuel has...

My LC1 is set to regular gas. Did my third free air test. My LT's are around +5% at idle, but steadly drops off to around 1% at 4000rpm, as it goes higher through the rev range. Can you change or...

Hi, Please could someone help me, i have been really struggling with this. My ecm is a E38 with 6.0L L98 motor, the car is an 08 Lumina SS. My LC1 WB in closed loop MAF reads on average 14.20 AFR,...

Before I comment, I am a great supporter of Greg, I have bought both books and DVD and have learned a lot. "A must have for beginners".

My question though to Greg (or anyone interested), is...

thank you for the feedback.

I have just notice a parameter in the e38, {B2105} which has the choice of been set to either fast or slow. My car is currently set to slow. I am running in SD mode with everything enable except MAF....

gameover, thank you, i would never have found it. should i set the values higher when i am setting vve (MAF is disabled as per tutorial) and once vve are calibrated and i start calibrating maf go to...

I have a L98 6.0 Chevy lumina 2008 (Holden) e38 ecm. I can't seem to find B0120. How do i ensure that i stay in MAF across the rpm range. I am busy calibrating the ve tables as per the tutorials and...
