I'm looking at buying a 90 Camaro that started life as a LO3 car running a 746. The owner has put in a 94 Vortec motor with a Whipple Charger. Needless to say, it doesn't run well. Can I fool the 746 with a two bar MAP and changed injector constants to get it running, or do I immediately have to dive into a ECM swap? Thanks for the help.

 

I can e-mail you a bin that will work better for a temporaray fix if the current one is stock. Do you have away to burn it though

 

I'm setup to burn. I've done a lot with my 165. What's been done to your bin? Are there any ECU files out there for the $61 or will I have to get it from tunercat?

 

Any other advice before I make an offer on this car?

Your in for grief.
Whipple is a joke for patching a system together.
You can use a 749, but it's a port ecm, and would take some serious work to work well with a TBI system. I've run a TBI off of a 730, it can be done, but it will be work to get right.

There is a huge difference from close to right when using a blower. If you want to paste things together a FMU and MSD boost retard will at least let you safely run some boost.

I think the BEST answer is adding fuel rails and port injectors, convertting to a high pressure fuel system, and using a 749, but damn that's alot of work.
