Hello guys,
I just recently purchased a Holden VX LS1 and the original Ecm was locked via tuner before me. I was having major problems with the rpm's hanging on and pushing the car and causing front wheels skidding. I spoke to several people and advised to start again with a new ECM. I have done so but having problems sorting it out. I have found a std Holden tune from a with the same OS system 12202088 Cal 92105179.
We are not sure completely of all work performed, It has a cam but unsure of lift / duration etc, it has the MAF removed and OTR fitted. pretty sure that's about it apart from the 3.9 rear end setup.
I am now starting from scratch engine runs but is ramping all over the place, trying to sort this tune out. I tried going to COS3 but for some reason i couldnt get it to run. LS1B.ctzLS1B theft off after cos 03 new parrameters.ctz
These are the 2 files the LS1 COS is with the EFI Custom operating sys and the LS1B is the new std file from an LS VX Holden 2001
Please Help
