    Power FC Installation - Ignition not turning off? Hey guys, I recently installed an Apexi Power FC on my R34 GTR and I eventually got it to self calibrate to a stable idle although when I go to turn off the ignition, the engine continues to run for another ~10-15 seconds (stalls itself) and the dashboard lights remain permanently on. The only way I can turn the ignition off is to disconnect the battery. If I remove the Power FC and re install the stock ECU everything is fine and the car's ignition turns off like normal. Anyone have any experience with this problem or know a possible fix? Cheers, Nick.

    Yeah the old ones are pretty far gone :/. I might just install the -9s then and keep the car off the road for a little longer until I can get injectors, ecu etc. Thank you for you help though

    Cheers for the quick reply Dan, I appreciate the effort too. Yeah I plan on getting injectors, ECU and a fuel pump later down the line but I will definitely keep this in mind . In regards to running the -9 turbos on my current stock setup (stock injectors, pump etc), should running 0.8 bar be safe in terms of fitting within the stock injector's/pump's limits? even though it seems as if they were maxing out on the old stock turbos?

    Safe boost levels for -9 Equipped R34 GT-R Hey guys, I recently purchased a pair of GT2859R -9 turbos due to the stock ones having blade damage and needing a full rebuild. I was wondering since the new turbos provide more flow, what boost levels would be considered to be 'safe' on a completely stock RB26? I previously ran 1.00 bar on the stock turbos and the car seemed to run fine although I did notice the injector usage getting close and hitting 100% which makes me slightly concerned for the new turbos. Do you think the stock boost of 0.8 bar would be fine or possibly even less? Cheers, Nick.

    Thank you for the reply. That does make sense now that I think about it . I will get in contact with a tuner within the week coming and I have had air leaks in the past so I will make sure to inspect the whole system properly. Again cheers for the help, Nick.

    R34 GTR - Misfire/Stuttering Hey guys, Over the past couple of months I have noticed an increase in misfires while coming on boost/just before boost. Initially it was mild yet when it happened the 4WD and A-LSD error lights would toggle on in most cases. Now every time the car is driven I experience the misfire. The coil packs and spark plugs were swapped out for new ones just under a year ago so my initial thought was that it could not be them. Boost is also very inconsistent in when and what boost it hits. I also noticed that in 2nd gear for example, there is barely any boost (0.4-0.5 bar) before 4.5k rpm and then at around 5k it hits really hard (1 bar) and causes the car to jolt suddenly. I do know that the stock turbos currently installed are in poor shape having a whining noise so I wasn't sure if that had anything to do with the problem but I am planning to swap the turbos out next week hopefully. Has anyone had something similiar or know of a fix? Thanks, Nick.

    At full throttle (while driving) the MFD percentage readout still jumps from (100%-99%-100%-98%-99%-97%-100%) very rapidly. With the car off but in 'Accessory mode' the readout on the MFD is very smooth without any kind of jumping or hiccups and is very accurate to the position of the throttle. I did notice that when I am measuring the voltage of the TPS, it drops significantly when I start the car which tends to trigger the '4WD/a-lsd' error lights on the dash so for the moment I have set the TPS voltage higher than the 0.5V (closed throttle) recommended. The Battery voltage on startup is around 13.6V which I think is low compared to what I normally see which is at least 14.2V.

    R34 GTR MFD - Throttle Percentage Unstable/Erratic Hey Guys, I have noticed during the last few weeks that the MFD throttle percentage display has been noticeably erratic in which the readout is jumping +/- 3 or so percent (flashing almost) while the throttle is steady. I replaced the TPS and the problem continues. While the car is not running but in 'On'/'Accessory' Mode the readout is smooth and steady with no fluctuations at all. Does anyone know of a fix/solution? Any help is appreciated, Cheers Nick.
