Hey guys, I'm having idle issues where I can't keep the car running and it never seems to want to catch. Either it runs too rich and dies or runs too lean and runs very badly. I have to keep steady pressure on the throttle to keep it from dying. Clearly that means that I need more air, so I would lower my VE values and it wouldn't seem to help any. The car ran better and would actually idle around 600rpm with all the idle valves on the plenum, but none of them were wired up. I've since took them all out, as well as the egr valve, and blocked all the holes off. I have my tune and a few datalogs. The datalog labeled IDLE(not idle1 or idle2) is when the car had the idle valves on the car but not wired up to anything. The others are without the idle valves. My injector PW seems very jumpy as well as the dead time. I have them grounded directly to the MS. They are low z injectors so I chose to limit the current in TunerStudios instead of using drop resistors. I made sure no ground wire or sensor wire was in contact with any noise issues(dizzy, spark plug wires, coil). I messed with the ASE and WUE to try and stabalize my afr's and keep the damn thing running, but I've had no luck with it so far. I have an MS2/Extra v3.57 Firmware 3.3.0 straight from DIY.

Hello. Im fairly new to the forum but i need help with my megasquirt. I restored and engine swapped my 260z and its finally time to get her running. I bought and assembled my megasquirt. I also made my own wiring harness with DIY's harness. Im almost positive i havnt made any mistakes along the way however the actual tuning part of the ms2 boggles my mind and i have no idea what im doing. I need a map that i can get my car running on for now. It is a stock block with a fresh rebuild, p90 head,stock distributor with DIY' trigger wheel. stock turbo injectors, stock turbo and psi, 240sx throttle body and tps, walbro 255lph inline fuel pump, i have bypassed the fuel pressure regulator for now as it wasnt allowing fuel though. I have messed arounf with some other maps i found on the forum but none of them are perfect. I want to say my firmware is the latest for ms2 extra. i belive i have the pcb 3.0. i will atatch the tune i found and am looking thru. Anything helps thankyou. CurrentTune.zip
