hey. i'm going to be swapping a jdm h22a into my lude soon and i just wanted to get a few things clear. first of all, i've read that the jdm h22a ecu has a speed limit set at 115 mph and the usdm ecu doesn't. i would like to go faster than 115 for special occasions so i'm thinking i would probably go for the usdm ecu. does the usdm h22a1 ecu have any down falls to it when used with a jdm motor? also, if anyone would know of a good place to buy one it would be appreciated. thanks

No you'll be fine with a USDM P13 OBD1, and I thought the speed limiter was 125 for the JDM P13, but I could be wrong.

joostdyk

alright, cool. yeah, i'm almost positive it's set at 115. i'll try and find a usdm p13 ecu then. any places to buy one?? i know ebay...but anywhere else?

i dont think the jdm ecu is an even MPH limit. its computed in KM/H so it is somewhere around 115-120.

You are right I checked around it is at about 115. In KM it's a little over 180.

My fuel cuts off at 120mph, feels like it hurts. Try a junkyard.

Hi guys i can reprogram the JDM p13 ecu to remove the speed governor. Let me know if any of you are interested. Thanks.

joostdyk

hey, i'm interested! i'll probably get the jdm ecu when i buy the motor, so it would be very nice to know how to remove or change the speed governor. whenever you get the chance, it would be much appreciated. thanks

joostdyk

:dunno: does anyone else know how to do this?

WHAAATTTT!!!??? the jdm p13 has speed limiter?? what about the jdm p72 from the gsr??? im thinking about using that on my h22.
