Here's the deal, i have a ZR2 S10 that i put in a L31. It is basically a stock engine with headers, CAI, bored .030 over, and the biggest change would be the cam, 431/451 (Ramjet 350 cam). I got my tune done with HP, it was totally messed up the first time. I sent it back and recieved a slightly better calibration, but still off. Since the guy who tuned it originally, left it unlocked i sent it to another guy i know who has the same motor and truck as me, but he has EFI Live. He says that the spark( timing) was way the hell off for this motor, and that there is a ETC section to it. The VIN that was programmed into it goes to a 01 Silvy 6.0L. I am assuming that the tuner again tuned it wrong. This tuner is supposed to be very reputable, and has tuned many FS trucks. I guess that is my problem right there, LOL...

Anyway, all this rambling with no substance. The guy who is now tuning it says that the tach won't work properly without a tach module. Why is that? I know guys are having to use it, but from what i understand with HP the tach was fine, why is it not ok when tuned with EFI? Shit, for all i know that tach was off with HP, but i was never able to drive the damn thing because of the messed up tune that was in it.

I do not have EFI Live at the moment, so i can't post up the log, or file. I wish i could. I can't seem to locate a used V2 or even V1 for that matter. these things are like GOLD, noone wants to part with it. I couldn't even find a used HP tuner. I know I know, just buy a new one, Just a bit out of my price range at the moment. But now that it has been tuned with it, i will have to get one if i want to make any adjustments later on.

Is blackbear the only person around that will lend you there black box logger and do a mail order custom tune?


I guess this is my introduction.. LOL


Thanks,
