Hi guys,
i was tuning a car on the dyno in SD (MAF disabled) using VCM OS 1271005 version and i reached to a point where the ecu was running the timing off the idle spark advance table...

It might fix the view and the cylinder airmass reference view on the scanner, but did i point out in my past posts that i tried setting both HO/LO timing maps to 10 then tried 25 degrees? well i...

now after tunning in SD and i want to leave it as SD should i revert any 284-285 values back to stock? well you know the settings i used to set the ECM to open loop (SD). i'd like to keep the vehicle...

Here is what I’m going to do next:

1- Remove MAF pid from the hptuner scanner table display
2- Set P0101-103 SES enabled and error mode to 2 - No Mil Light
3- set the cylinder volume to 0.75...

i set the PE tables to 0.9 in purpose! i started with 1.3 all over the PE table and then 1.8 and noticed no effect from the PE tables, so i was curious if the ECM was going in PE mode or not and set...

YES MAF is failed (zero'd out) and i had to tune my VE from the secondary tables. i dont know about the timing reference and which the ECM is following, but im running both high/low timing tables the...

by the way that print screen of the scanner timing advance table is when i was doing a WOT....does it seem my MAP settings are wrong? where should the readings reach to? the ecm goes at full throttle...

so you are telling me to use the 12212156 OS? which vehicle year model is that? in summary my issue is that the car doesnt go into PE and doesnt follow the timing tables of the high/low tables!

if...

disconnect the knock sensor and see if you still read KR then you'll know its a sensor issue or tune issue. if the EMS still retards with the knock sensor disconnected then you know the issue is in...

remove the maf pid from the histogram display or from the table display (please refer to the photos i attached)?

hi,
Yesterday i was trying to tune a L96 6.0L silverado engine that was transplanted in a 4wd vehicle. Used a GM firebird/camaro v8 1999 ecu to tune the engine. I usually do speed density tunning...

when you say a new OS do you mean a new base map OS from the donor car or you mean a newer version of the ECM im using? i will post this in the gen3 even though the engine used is a 2011 year model...
