THe MAP sensor only feeds the boost gauge on the dash. Did you plug the hose when you disconnected? Sounds like it's the idle air control but you've tested them. Does it blow soot all the time or only at idle? Checked the timing? Maybe the cambelt slipped a tooth?

Just fitted a black SAFC-2 to my R32. I already had a digi-dash fitted where the ashtray was so I mounted mine behind the steering wheel, about where the auto PRNDL display is (below the wiper switch). Barely fit. Now I have to sort out the tuning... but since I hardly have any mods (yet) I don't expect I will make much more.

You sound like my clone, even up to the 20psi boost once! Except I have a high flow cat. My next plan is to fit the SAFC2 I have lying around, then find some GTR injectors and a bigger BB turbo - but my budget is just as tight as yours.

Where did you find a 2002 GTT?

Got mine a couple weeks ago and installed it in 5 minutes, down in front the ashtray angled up. Works great - I have to try the datalogging software this weekend. About the oil press/oil temp/fuel press, maybe you could include a couple of analog inputs for things like these, that don't come from the ECU. Just a thought.

There are some small hoses connecting the front of the manifold to the back and the turbo coolant line. Probably one of those. You'll need a little mirror and a lot of light. I've had 2 burst at different times. There's also a metal pipe that runs from the top radiator hose joint to the manifold and connects in 2 places. Hope it's not that.

Hi guys, Dunno if this will help or just add to the confusion - my RB20DET has been giving me grief with this over the last 6 months. I don't know what to do anymore - I'm frustrated and miserable Car started with the occasional erratic idle, just out of the blue. I did some research on SDU, did the AAC cleaning, fiddled with the idle speed screw, did some research in the engine manual (I have a pdf I got from a guy online somewhere) but I couldn't find the cure. Eventually a couple weeks ago I took the car to a guy who's supposed to be one of the top mechanics at the Nissan dealer (they let him borrow the Consult to work with at home!) and he did a diagnostic with it and found nothing. I think he tried setting up the idle and the mixtures with it, but it didn't work. He told me I should change the plugs. Went and got some Denso plugs (the equivalent ones to the NGK PFR5a-11 that's the original plug) and took out my Denso IQ20 Iridium plugs (they looked almost new, just a shade of yellow/brown on the insulators ) gapped them to 0.8 and put them in. Saved the Iridiums Started her up and it was running well, just a little high rpm, so I decided to check the throttle position sensor according to the manual. The readings are supposed to be 2k ohms with throttle closed and 10k wide open, but the best I can get is 2k ohms closed, 8k ohms wide open, and that's with the TPS fully twisted to clockwise. Set it back where it was before, but now it idles at 1200rpm Disconnect the AAC plug to adjust the idle, and it drops right down to 700rpm. Plug it back in, up the idle goes to 1200 again. So now in order to get it to idle at 1100rpm the screw in the AAC valve is all the way in. I've cleaned the engine temp sensor terminals, changed vacuum hoses and had a listen round the engine to see if I can hear any air leaks - there are none. The car runs ok mostly, but now it will occasionally and for no apparent reason run REALLY F--KING RICH to the point that it wants to stall - this is in any gear. Oh, and it has a real bad backfire at WOT - probably stuffing up my poor stock turbo, since I found a bit of oil in the J-pipe. At my WITS END with this. Seriously considering selling the thing - I went and test drove a Dodge Ram pickup last week :Oops: Any suggestions? I'm wondering if I need a new engine harness - maybe there's a bad terminal or a wire break somewhere. I should say, the car has some minor mods - Greddy Airinx filter, GTR front mount IC, DSM manual boost controller @ 12psi, 3" exhaust, Greddy 1mm metal head gasket (legacy of a warped head a while back due to overheating), manual gearbox conversion.
