air flow meter, its starts with that and gets worst and worst, untill your catr starts stalling, borrow one of a working car, put it in and give it a test drive, if your car runs fine, then buy one, ive blown a few of these in my times,

Hey mate.. pmed you..

You should also check

- fuel pump relay.. if there's been an instantaneous break surging may occur..

- the injectors.. the drive circuit in the injectors could have short circuited.. causing misfire and over rich fuel/air ratio..

- Spark (ignition) .. may be a misconnection of the high tension wire .. may cause surging during acceleration, cruising, may cause engine to stall at idle, whilst driving, during deceleration .. also check your fuel consumption.. because it's a big indicator as to whether its the sparks or not.. excessive fuel consumption could mean it's the sparks..

Keep us updated..

    • I'd need to check my notes at work Duncan, but I'm pretty sure most of that is purely OBD2 on the display. How quickly is it all able to update? Do you have any internet capability in your workshop with a laptop?
    • Yeah just gonna be near stock runner only want 180kw to 210kw can’t find anything been looking ages looked in to rb25 but money is tight as the moment need the car back on the road 
    • From there it is trickier. Ecutek seems to be one of those closed ecosystems where everyone password protects their tunes which means I either choose a tuner and can't change from them and can't make any changes myself for any reason, or I have to buy the tuning software (about $4k) and then get someone to tune from scratch (which is not simple with all the multi dimensional tables these days). Once you buy about 300 "flash points" per ECU you can get it tuned and add their "RaceROM" function which hacks extra functionality like launch control onto the ECU, and also makes extra data available for logging over CAN Not sure what I'll do there yet; I'm tempted to use one of the overseas shops that does billions of remote tunes of the platform instead of starting from scratch locally, a lot can be done online these days.
    • Can I log IAT eh? Well, can now So next thing was looking at data logging. Not straight forward because none of the motorsport displays have cracked the nissan/inifinti CAN and ECU based displays don't do g logging, lap timing, predictive laps etc.  So, I bought an Ecutek dongle from Tunehouse (Oz distributor). Even without a tune onboard that allows display and logging of about 50 parameters via Android (and presumably iOS) app. Approx 600 for the bluetooth + Usb version That gives me (pretty ugly but) functional dash display on Android And logging of these parameters I'll play around a bit over the break, but at least now I can make sure I have oil pressure when I get to some track testing.
