i have a s2000 ecu... it says 37820-PZX-a02
on it... what yr is that from >?

also have a s2000 cluster... > revs to 8gs, has to plugs in the back of it > how can i find out the exact yr it came from >?

there should be part numbers on them some were, match those numbers online and im sure you'll find what year it is out of.

 

CRX si69 is right...also if it revs to 8k more than likely its from an AP2(04 up)....

 

Narrow it down by looking at the temp/fuel gauges

If you can't figure out it's not an 00-03 I don't know what to tell you.

 

OK... ecu has to be 04+.
whats the diff 00-03 to 04+ ecu... i know 00-03 revs to 9k and 04+ revs to 8k...
Is there anything else Different ??

 

There are also the 06+ to think about those ECUs run the S2000 which are drive by wire.

 

00-05 drive by cable 06 and greater are DriveByWire, 00-02 ECU run richer than the 03(runs lean)...00-03 ecu's redline is at 8.8 or 8.9k with fuel cut at 9.2k, 04 ecu's redine at 7.9 or 8k fuel cut at 8.2k

 

thanks,......

 

I think you'd get a better answer if you said what youre trying to do instead of asking dead end questions...

 

Sooo is this a 04 ecu > 37820-PZX-a02

 

NOP....if its 37820-PCX-A02 its from a 02-03 S2000......so yea your ecu is from a 02-03 S2000 since thats what my 02 s2k has..... and bout the cluster... im not really sure but sure its from a 04+ s2k since 00-03 rev up to 9k rpms....

 

you would be out of luck if you have an 00-03 ecu with 06-up cluster...mainly because of drive by wire
