Stock ecu with nistune

I'm having the same issue and I've tried 3 x s13 and cefiro stalks and all where different. The cefiro stalk made the Parker lights stay on. Weird. Let us know if you find the issue

With mine I have left and right toggle near the sunroof. Left to open out when closed and right to close it. I then have to release the button and push it again to open the sunroof in to the roof lining. Mine stops about half way I then have to relase the button and push it again to open it the whole way open. Hope this helps. Billy

Thanks RANDY How can I tell my HRN model?? My ceffy is a factory 5 speed RB20Det, Black, Sunroof, ABS, HICAS or 4WS, Rear wiper. What else do you require to work out what the HRN model?? Cheers Billy

Hi All I am after a part number for a full ECU loom in my 89 Cefiro can come tell me this CA31 700-800 is my vin number. I'm seeing what the price difference is in a new loom.

Does anyone have contact with a Nissan parts adviser, my local dealer is hard to deal with. My vin is CA31 700800 (cool vin hay) I am after the part number, cost and if their is one available in AUS for an ECU engine loom for a 89 Nissan Cefiro factory RB20det.

Our local nissan parts are a bunch in their own. I have asked the quetion and await there reply. Fingers crossed.

Yea can drive through it in on light throttle. Fuel pump has now got a direct power supply from the battery in the boot. Would the CAS (crank angle ) give this sort of issue?? It's the only thing I have yet to replace?

Is the wide band what they usually use on the dyno? As the fuel line is perfect on the dyno run. I can hold the throttle flat and it will hold revs at 3000rpm until I pump the throttle through the flat spot.

Ok it did run like a dream now I'm having the same issue and I have changed about everything I can think of tps, afm, coils, spark plugs,injector clean, fuel pump, fuel filter. It ran fine on the dyno and when I took it to the track and it fully warmed up it start getting a flat spot and surge at 3000rpm and thing else I can try??

Does anyone know where to get a new rb20 wiring loom from??

Have found that it was low volts to the fuel pump have rectified goes like a dream now.

16psi and NISTune. I changed plugs cleaned afm and still nothing. I'm going to try change the z32 afm and see if it's that also.

Pump just replaced, no smoke. Will be getting looked over this weak for tune. It spits and farts when it hits 3000 rpm. I will give the afm a clean again. Thrilled doesn't stick when I free rev.

Hi all I am getting a flat spot at 3000rpm I release throttle and step on it again and it revs through it. It's all the time not on off. I have done the usual checks. Any one have any thoughts?? Billy
