I have a shop that has a spoon ecu that came from some motors from japan.. its genuin has the spoon tape seals and all but my question is what is different from my us spec h22 ecu higher redline? fuel cutoff? etc...
background info:
93 prelude
engine 94 h22 usdm, I/H/E headwork with ported IM, vafc... im still building the motor so modifications dont stop here

 

The ECU is not just chipped, it has its own stuff.
Yes, has higher redline, better air and fuel, and not sure, but might move the vtec x-over.

 

I have two different variants of the Spoon program, but both are very simliar (Spoon does that usually to all of its ECUs)
vtec points seem to be in 5-5.3k rpm range
rev limit in 8.2-8.6k rpm range
fuel maps and ignition maps are also improved (for once spoon acutally made a good streetable program which makes power)

 

but i have a APEX'i VAFC so taht covers vtec and fuel map right? so all i would gain is higher redline and maybe higher or aliminated speed govener?

will this uce dampen any tuning i do on the vafc also?

 

Yea you're correct all the prog is going to do really for you is remove the speed limiter and raise or remove the rev limiter but it dose also have control over the timing maps... The new prog most likely has upgraded fuel and timing maps which will affect you if you have your VAFC tuned for your setup right now... I personally hate the Spoon progs, but that's just me... I would just stick with your VAFC, unless you just want to raise/erase your rev limit or speed limiter.... Latez
