I installed my j-spec ecu earlier this week and today went for a top speed run and at about 115 the car sputtered real bad (scared the s--- out of me I thought I blew it up) so slowed down and accelerated again (not up to 115)and all was fine any one any ideas ? iam affraid to try again

what ecu? i know the kl-31 has a speed limiter at around 180km/h IIRC, not sure about the kl-36 though

kl-36

My KL36 supposibly had a speed limiter, but Lazzyie removed it. Kp2t has a KL36 ECU I believe, and it has a limiter around 180-190 Km/h.

It should be removable by cutting the "Speedometer To ECU" wire listed in the Online Shop manual, but I don't know of anyone who has tried it.

to remove my limiter, I did this..

Cut that wire It is coming out of the medium sized (22 wires) plug going into your ECU and the diagram is as if you were looking into the plugs on the ECU (wires are coming towards you).

Yep, that's the one, Shop Manual page F2-144/145. 1M Vehicle Speed Sensor.

do u know what color the wire is? (this is bull!!)

The diagram I believe says Green/Red, but the marking 1M should be on the ECU.

AAA THATS THE BP engine..says B8 .... not k8

You may be right, but it's still 1M. Check the online manual F2-148

oh i know what im talking about..lol

Yeah KL-36 cuts at ~115 mph.

I don't remember the pin number i cut on my 1993 MX-3 GS, but it removed the speed limiter completely and no CEL, or ill effects..

But i remeber the wire being way smaller gauge then the rest and i think mine was black and white. I'll get back to you on that.
