im not sure the wiring is much different to the power fc than the haltech, but again im not a tuner nor did i install it so i would only be guessing.

the io expander makes you have more configurations you can use with the Haltech. again im not a tuner but to me that sounds like a good idea.. im only guessing its for making different tunes and being able to save up to 12.. someone correct me if im wrong.

im with you jamie, i never got this "random cough" thing either. but i can say the car drives alot smoother with the haltech.

Best thing I ever did was get rid of the pfc. My link g4 drives sooooooo much better

It's not about the extra hp, it's the features and how much nicer it drives It's like comparing a 500hp HQ and a 500hp VF commodore I know which one I'd rather drive every day

But isn't the problem with the design if the engine itself? Ever seen an RB in a dyno without the cam gear cover on? The belt flops around like nothing else. That "flopping around" must result in some

As for random coughing on power fc, I reckon it's a GTR thing.

4 of GTR's I have/had they all did that. My wrx which also have power fc, it doesn't cough nor my mates wrx.

I'm in 2 minds whether to bin the fc in the R for some map based ecu.

Probably questions suited to another thread but does one get cough while running with Nismo afm?

If your car has a cough you will know about it. Ground wires helped, I might get 1 every 2-4 tanks where before I would get a few every tank. I have a dejetro

If you have a later model car, you probably have better earths and less dry solders which seems to be the culprit

Unless you have driven on a higher/high end ecu you you will NEVER understand! Dont get me wrong a power fc will serve its purpose but its the lil things a dyno doesn't Show you but it all happens under the right foot.

At least a pfc still reads timing like it should. Other ecus have intermittent issues with the 360-6 cas. That's why people should have funds for a crank trigger just in case.

Without crank trigger

With crank trigger.

I can't remember now if the without crank trigger was done on the FC or the Link G4, it's been a few years since I put that on. Either way, that timing variation with the timing taken from the CAS is woeful at best.

Both graphs taken from my own car.

Good thread, subscribed.

I am currently using a PFC with 480hp (soon to be 550hp). Considering the swap to the Haltech.

A map sensor would be nice, due to the need for AFM's I am constantly battling "PFC disease"/ airflow reversion though the AFM's.

what good timing, im considering the exact same move, got Adam@JEM to quote on Haltech supply / tune and perhaps booking in next week

wanting fatter midrange, and e85 for anti-det, im running hks gt-ss, 720cc sard, nismo afm, nismo fuel pump @ 320kw

oil pressure drop protection is also appealing, im already running wideband, so would be good to feed that into ecu as well now

few Q's:
i run blitz dsbc boost controller, do i need external haltech 3bar solenoid or existing can be re-used without -ve impact?

map vs maf, is there a noticeable difference to throttle response if i switch the map?

anyone running nismo fuel pump on e85 or walbro e85 fuel pump a necessity?

I don't know what my point was.

Maybe it is just saying map is better than maf or vice versa isn't enough.

A shit ecu is a shut ecu regardless of what it uses to measure load. There's a reason factory cars use afms, even now (r35 gtr etc)

Popping cooler hoses shouldn't really be a deciding factor in choosing an ecu.

Popping inlet manifolds that's where it's at.

Back in the day I had a wolf 3d v4 on a vl turbo (map sensor, so it was good???)

Running extra injectors pre plenum (old days ghetto as, no cheap injectors like you spoilt kids)

Backfire, exploded plenum, ruined bonnet.

Due to having a map sensor car accelerates flat out atmo style (not concerning)

I simply set rev limit to 3000 rpm and drive car home like a boss.

Do that with an afm. Yeah, explode shit and keep driving.

Popping hoses is soft.

      Unpeeling the Orange

      Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.

      No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.

      Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).

      I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
