get the proper chip burned for my Chevy TBI on my AMC 360. It's running very rich and has never been right according to the guy I bought it from. He didn't know the cam specs and he and the TBI guru guessed at it. He decided to go with a LS1 and sold me the 360. Any advice would be appreciated. TIA

Check out tbichips.com. This guy seems to be pretty knowledgeable and pretty helpful. You can do a google search and find some places to.

I second tbichips.com he is pretty good

Without the cam specs it will be guessing. unless you hook up the appropriate software and read the codes and how it's running now.

A good way to go may be to jump to megasquirt and replace the stock TBI computer all together. It will interface with all the stock components without too much hassle, even if you are using a computer controlled HEI dizzy.

Being able to custom program your computer rather than relying on somebody to guess at a map from halfway accross the country = priceless. Cheap too.

Thats my plan for the 360 I have.

For about the cost of having some one else guess which chip you need, you can buy the equipment to do it yourself

unless the cam is really wild, I don't think it's going to have -too- much effect on running "really rich".

to me, it sounds like the ECU is running open-loop...i.e. limp-home mode....perhaps a bad O2 sensor?

...or it's a stock table but the engine has REALLY large injectors in it ??

I do agree that you can (should) get set up for tuning it yourself (and other engines that you do in the future) for about the same bucks as paying someone else to mail you a chip that may not even fix the problem.

Please remember to report back with the solution when you get it fixed!

What ignition system are you running? I've had experience with the AMC/TBI combination and the OE Ignition doesn't always cut it.

I have the autoprom kit and am working on my own chips. If you have an aptitude for this stuff you will be further ahead in the long run.

FWIW: I'm runnig a carb cam in my 307 (chevy) and first thing off the bat I had to cut fuel in the low end of the VE (volumentric efficiency) table. A carb cam profile is lumpy and at idle the ECM thinks its under load and adds more fuel.

good luck
