I have a LO5 rebuilt motor bored .040, ported heads, mild cam, etc., etc. It makes 315fwhp and 390ft/lb. I bought it as a crate, it came with a bored TB and manifold, and a chip.

I would like to get a whipple blower for the motor, however, I would need to have a custom PROM burned because the ship that is supplied with the blower is configured for a stock LO5.

Is there a solution to my problem that doesn't involve me burning a chip for my car? If I were to give the specs of both chips, could a chip be burned without data logging and doing it all myself? I understand that it wouldn't create the most potential power, I'm just looking to get the car up and running to be able to drive it somewhere to have it tuned on a dyno to it's full potential.

 

The stock ECM wont work with a blower. It cant see boost. The only system thats available for a reasonable price that will work is the EBL setup being discussed over on the DIY-Prom. Youll most likely want to tune it yourself. You cant really tune without datalogging. Its nearly impossible. Its also likely that the dyno-tuner will be lost when he goes to tune it as the EBL is all new.

 

It doesn't necessarily need to see boost. I have sucessfully tuned roots/screw type blower using a vacuum signal from above the blower. The boost at various RPMs and MAPs will be really consistent.

 

I assume your reffering to the vac above the tbi that results from the pressure drop? Its hard to resolve the boost without actually having the pressure that the engine is being subjected to. Multiple modes of engine operation will overlap eachother in the tables without a 2 or 3 bar MAP reference. With the tools available now, I figure one might as well go ahead and buy the right hardware.

 

Agreed, but some of us were toying with supercharged TBI engines before the hardware was available. Search for thesupercharged, ported 193 head 305 TBI that I built and tuned for one of my buddies.

 

So I guess I have to learn how to tune my car... or not get a blower then
