GSR swap - stock ecu - speed limiter?
So my GSR swap is running great now after a few problems.
Weird thing though, yesterday, while on a particularly empty stretch of freeway, I realized that at ~115mph or so the car very abruptly looses power until it gets back below ~115mph. I know I really shouldn't be going that fast, and seldom do, but I want to know if this is normal....
TIA

Yes it is normal. That is the speed limiter cut off and a chip will solve that if you need to take it off.

usdm p72 's have speed governor? no way, mines only have rpm limiter
to my knowlegde only jdm ecu's have speed governors

Damn, how can I tell if my ecu is USDM or JDM?

So then the question is: are there any other differences betwen USDM and JDM ecus?
I have a USDM motor btw...

JDM ecu will be a small case type, while the UDM is a larger type (like all other USDM OBDI ecus)
also USDM barcode will read 37820-P72-A01 or A00 or C00 or C01 or A02 or variation of that.
JDM do suck big time, I dynoed two different motors stock for stock JDM to USDM you you will see about 10-15whp and 10lb.ft of torque difference all in the low to mid range 9up to 7k rpm).

Damn, I'll check the serial number. If I do have a JDM ecu hopefully I can find a USDM OBDI P72...
