if i buy a ebay chip can you use this in a prelude ecu? the ecu is a p13. thanks

 

JDM chips don't work on USDM ECUs...and vice versa. Somebody correct me if I'm wrong. P13's are relatively unchippable...

 

That's correct based on what I've been told too. For some reason, JDM P13 programs only work on JDM P13 ECUs and US P13 programs only work on US P13 ECUs.

The US P13 can be chipped. There are several good programs out for the US P13. I used to have a Dinan-chipped P13 that I just recently sold. That ECU was a great improvement in my otherwise-stock 1993 Prelude VTEC that I used to own.

i have done a hondata install with the chip and all, but what do i have to do with the p13 to put a chip in it?

 

Hondata can only do Stage 1 on a P13...so that's fuel and ignition timing, rev limits but that's it...no boost...no speed limiter (JDM). I guess the same as Dinan...

Somehow they can't get to Stage 2 levels or use the interface box...weird.

 

I Reprogram ecus for both the jdm and usdm p13's. They are chippable.

 

Well suck me sideways!! Isn't that nice...I wish I had know before I bought a P72!!!

Why can't Hondata do it?

 

sorry bout that! well the p72 isnt too bad. The reason why is the format is different on the p13 ecus they run a different board. The other b-series ecus are compatible with hondata because they are all on a similar platform. Hope that helps!

 

when install this chip do all you have to do is put in the socket and the chip? or what? thanks

 

You must be confused here, Joel. You already knew the P13 was chippable. Yoshio will custom tune P13 chips if you want. Hondata still doesn't offer stage2 P13 systems, because it's not worth it to them.

 

Oh yeah, the techtom stuff....right!
