Help! Rebuilt KA need to know how to re-tune ecu

[curvejunkie]

Hey Guys, Newly rebuilt KA, Lighten up everything, upped compression, ported and polished. Here's the question, what, how, where, re-tune ecu. Not sure what my choices are for a ecu tune. It's a '96 240. Thanks for any help

If you're a do it yourself kinda guy: nistune, calumsult, bikiromIf you're a plug'n'play kinda guy: EFI Specialist, Jim Wolf Technologies, Enthalpy, Emance.

I'm sure that I've left several out, also I make no claims of the quality of any of the options (I have no personal experience with any of them).

I may be wrong here, but I don't see anything listed that would require a retune.

The ECU is plenty capable of adjusting fuel delivery as needed.

You're not adding significantly more air (forced induction). Drive it.

I think a bone stock 240 could benefit a little from a slight retune. I'm not talking any large hp numbers, just enough to be a little bit more fun.

I thought upping the compression required a re-tune? Even if it'll run without one he'll receive more of a benefit from what he's done by tuning accordingly.

Also, if he "lightened" everything and balanced the bottom end he should be able to rev higher, which would need an ecu tune to exploit that.
