Tuning a Foixbody with a KenneBelle

[FastFox]

Just installed a KenneBell on a 331 stroker motor. Car really pulls hard above 2000 RPM, but is really rough below that range. Really bad on fuel usage. I think a custom tune is in order. Coach me on what devices are available. We have a dyno tune shop locally. Coach me a little.

Pretty sure to use the stock computer you'd need a chip and someone that can (still will) custom tune it on a dyno, don't waste time with mail in. Other options are a Mega/Micro Squirt (I've got a megasquirt) and tune yourself or hire out, or a Holley which are supposed to be awesome but much more expensive.

KB will do a custom chip by mail. Just send them your mods and it will be close and safe.

I have a Moates Quarterhorse, a Burn1 chip burner, and a chip I will sell for $200.

Holley Terminator has a 302 ecm now

The Holley EFI is the shit. I have it on two cars. It will do anything you want it to do and then more. It ain't cheap though.

Sorry, but I think this is really bad advice. There’s no chance I’d do a canned tune especially on a Forced induction setup. A tune needs to be adjusted while monitored.

Your options are:
-new modern ecu $$$, it will still have to be tuned
-dyno tune with a SCT chip from a local shop, this can go bad - most shops won’t want to mess with it and if they can’t get it right they’ll claim you have a mechanical problem and send you out the door to get it off their dyno.
-Moates quarter horse and do it yourself. Steep learning curve.
-Moates quarter horse and pay someone to tune it remotely. There’s a few out there and they are weirdos.

Your best bet if you have the $$ is an aftermarket ecu and someone locally to help tune it.

Similar to the megasquirt that I have, good stuff, and Doug (Bluecouperedvert on here) can tune them pretty well if you need it.

Thanks for the input. I think a new system instead of the add on chip is the better way to go. I already have a gazillion in the car, but isn't it always like that with toys ?

[JV106]

The guys I know that have the pro-m swear by it and the owner of pro-m from what I understand will practically tune it for you.

Foixbody, I have nothing intelligent to add, but every time I read the title I think of a woman up north saying “foixbody”

[FastFox]

Sorry about the typo.
