Stock LS1 with powerdyne 6 psi kit

[hotrod]

Ok a friend just bought a 01 SS bone stock with a powerdyne 6psi kit NON-intercooled on it. He brought it straight to me and said fix it. lol Took it for a drive and its not happy at all. Sparks knock bad if you barley get in it. This is my first supercharged car and not sure where to really start. I pulled the tune and someone has been in it before but its not right.
It came with SVO 42lb injectors, 255 pump, and TR-6 plugs all not installed. I just put them in tonight. Its a suck threw MAFF setup and has NO FMU.. From what i've read i guess thats why they got the 42's and 255 pump. I looked for a good base on holdens site but there isn't one. Could someone set me up with a good base to start off of, i'll include the tune i pulled but i don't know if i need to start from scratch. I'll also include a stock 01 file from holden's site if needed.

Thanks Brad

Looks like a near stock timing table.
Bad.
Im no FI expert, but Id be taking timing out from 0.80g/cyl up.

Yes i do have a wideband LM-1

I have done quite a few NA cars but this is my first shot at an FI one.

Other than the timing tables being near stock how does the rest of it look?

Here is a tune I whipped up for ya, less timing in high load areas and more full in high load areas approx 10%, caled it for the 42lb injectors too. Should be safe, maybe overly safe. Hard to guess what your engine needs with out a log but this should get ya started. Would be better if your buddy could get a intercooler on there to help with IAT's.

Good luck,

may half to turn off map codes p0106 if they set. For being in boost at part throttle. You may also throw a p0101 for the maf sensor and may half to turn that code off too, but drive it and find out.

Here's an updated tune, forgot that the ls1's are 4bar, and your svo's are rated at 3bar so your 42lbers are actually 49lb injectors on this car. I updated the ifr table for you.

Ok i played with it and got it running really good. But the only thing i noticed on the wideband is on a decell when i let out of the gas it goes way rich for a few seconds then comes back to normal or untill the defco kicks inl. I'll include both the tune and a datalog. You can see a nice one at frame 1720
