Hey everyone, yesterday I wired up my Haltech Plug and play for my R32 Gtst with an rb25det swap, running 750cc intectors, topmount turbo, Haltechs MAP sensor (was running a used Z32 MAF with Nistune) And running an rb20det Engine harness without VCT pinned.  My problem is that once the car gets warm and has been running for 10-15 minutes it will randomly cut all power and stall out, I got it to do it a few different times and i know its not losing fuel pressure because my FPR gauge had full pressure when it died, I was wondering if anyone had the same problem? The car was running previously with NIStune and didn't have this problem

The injectors have been adjusted for, and air intake temp is turned off.  And I also know its not plug and play, its just a lot easier then using NIStune in my personal opinion

Nistune is easier to setup than a Haltech.

Do you even have a wideband on the car? there's a chance it's too lean and stalling/leaning out... also you need to play with the idle control PIDs to get it to idle + work on the fuel cut/recovery table? did you adjust the correct injection dead times etc.?

There's much to adjust and tweak before it runs properly. Nistune however, just drag the K and TIM till the car stoiches the rest is easy.

    • Yeah, it's getting like that, my daughter is coming over on Thursday to help me remove the bonnet so I can install the Carbuilders underbonnet stuff,  I might get her to give me a hand and remove the hardtop, maybe, because on really hot days the detachable hardtop helps the aircon keep the interior cool, the heat just punches straight through to rag top I also don't have enough hair for the "wind in the hair" experience, so there is that....LOL
    • Could be falling edge/rising edge is set wrong. Are you getting sync errors?
    • On BMWs what I do because I'm more confident that I can't instantly crush the pinch welds and do thousands of USD in chassis damage is use a set of rubber jacking pads designed to protect the chassis/plastic adapter and raise a corner of the car, place the aforementioned 2x12 inch wooden planks under a tire, drop the car, then this normally gives me enough clearance to get to the front central jack point. If you don't need it to be a ramp it only needs to be 1-1.5 feet long. On my R33 I do not trust the pinch welds to tolerate any of this so I drive up on the ramps. Before then when I had to get a new floor jack that no longer cleared the front lip I removed it to get enough clearance to put the jack under it. Once you're on the ramps once you simply never let the car down to the ground. It lives on the ramps or on jack stands.
    • Nah. You need 2x taps for anything that you cannot pass the tap all the way through. And even then, there's a point in response to the above which I will come back to. The 2x taps are 1x tapered for starting, and 1x plug tap for working to the bottom of blind holes. That block's port is effectively a blind hole from the perspective of the tap. The tapered tap/tapered thread response. You don't ever leave a female hole tapered. They are supposed to be parallel, hence the wide section of a tapered tap being parallel, the existince of plug taps, etc. The male is tapered so that it will eventually get too fat for the female thread, and yes, there is some risk if the tapped length of the female hole doesn't offer enough threads, that it will not lock up very nicely. But you can always buzz off the extra length on the male thread, and the tape is very good at adding bulk to the joint.
    • Nice....looking forward to that update
