Some would say boosting on a stock Honda motor with open deck, cast pistons, and pencil dick rods is pretty stupid too, but we're all guilty of that. :P

So are answers to questions that have no point or actual answer.

If you understand how the ECU works and how to tune a motor, the only thing you have to worry about is blowing out the MAP diaphragm and even then I dont think your engine will blow-up if that happens.

douspray

not to hi jack, but how would you know if u blow out the map diaphram?

i would imagine you'd get a map cel and you're car would run like ***. back to the stock map question, the stock honda map is actually 1.75 bar and is limited for tuning up to about 10.8-11 psi, but i too have run up to 15 psi with no problems.

Chris Harris

Stock OBD0 MAP is only good to 9.6psi....supposedly

Turbo242

i have a 89HF could i run uberdata or turbo edit on my current ecu or would that we pointless? does UD or TE even support HF ecus?

Chris Harris

What ECU is in the HF? Its a PM8 or something right?

Well, its supported for any OBD0 ECU (cept PR3/PW0) but chipping that HF ECU is another story.

Best bet is to find a PM6 ECU with an external eprom and chip that and run TurboEdit.
