I am trying to help a friend out with his hotcamd L98. No wideband on it yet, but maybe someone can spot something from our datamaster log. The car is currently running a PCM4Less tune.

If anyone is willing, great!

thanks

There aren't any DTC's shown, and under full throttle it shows about 5* knock retard, but that could be false knock because of the stuttering/popping as it breaks up.

Car has zero power, off the line, or from a roll. Even blipping it from neutral with no load shows some stuttering.

He says he has a Walbro 255 pump, stock TPI intake, ported heads, hot-cam, and MSD blaster coil. Plug wires look new but its not my car.

Matt will have to list everything done to his car.

 

He has the basics of whats done it has a stock rebuilt bottom end with ported heads, a lt4 hotcam, 24# svo injectors, 1.5 roller rockers, a BBK afpr with fuel pressure set at 44, only thing done to the tpi is the egr wall was taken down and it has no egr, the car also has long tubes into a x-pipe then dynomax bullets that dump before the axle, bosch style o2 from autozone, and a pcmforless tune, that I told the guy what I told you that was done to it. Any help from anyone would be GREATLY APPRECIATED, I've put so much time and effort into this this thing and put it together from a shell and would like to gain the rewards for what I have done. Thanks

 

I forgot the msd blaster coil, msd cap and rotor, month old accel 8mm wires, and accel spark plugs

 

Anyone?
