New engine.... tune questions?
New engine.... tune questions? Alright... I just got a new engine installed into my 01 ws6. It wasnt new but it was an engine with 30,000 miles that was rebuilt. My real question is how in the hell am I going to tune it? Should I break the engine in for say... 500 miles and then have it tuned or should I have it tuned asap?
Well.... this is the entire story:
Took my car to a shop because I knew something major was wrong. It turned out to be a crack in the block sleave. They tried to fix it but when they where heating it up/cooling it down.... it cracked again. So they got another block out of a 99 z28 with 30,000 miles that had pistons/rods already in it. They slaped everything back together including patriot ls6 stage 2 heads, cheater cam, and a ls6 oil pump.
The shop that did the install said they tuned it but I know the guy at the shop.... and he can not tune for ****. It is running real rich and when you get on it at 50% it does not feel right. But if I just drive it like a grammother then it seems fine. I just do not want to hurt the engine by driving it around without a good tune and at the same time I do not want to pay 500 for a dyno tune and hurt the engine.

hmm...well i thought you had a totally rebuilt motor...by what you say the rotating assembly has 30k miles on it...so no break in is needed, i wouldnt have liked a used bottom end....but just get it tund now
If they only replaced the shortblock, with the same H/C and everything else bolted back up. Why would you need a retune? It's going to be flowing the same amount of air/exhaust.

Just a thought; but you could get a Idle tune;part throttle tune; and then if everything felt o.k. a WOT tune. Conley's Perfromance Plus; Houston TX has real time tuning capabilities on Gen IV engines and this could be done with out damage to your engine as long as it has been propperly assembled.
What you do not know for sure with out a tune is AFR and timing which can both cause detonation and that is an engine killer. LOL
