Hi,

I have a R34 GTT running an apexi power FC computer,

After mentioning that I am going to a top mount Forced performance 3076 turbo I was told I should upgrade to a Haltec Platinum Pro.

E85 is not an option for me so there is no advantage there.

However the 2-stage launch control and flat shifting features of the Haltec interest me.

My boost is currently controlled by the PFC hand controller, but if I got the Haltec I would need to install another form of EBC?

I have also seen the map sensor only supports 1.5 bar of boost?

What advantage would the Haltec offer other than more tuning resolution (32x32 vs PFC 16) and the ability to ditch the Z32 afm

Appreciate any input and discussion

Anything that gets rid of the air flow meter is a step forward

Do not underestimate how much of a big deal no AFM's are.

Also I just upgraded to a haltech in my R34 and I couldn't recommend it more. Yes it can fully control boost if you buy the boost control solenoid and you can buy an external MAP sensor that will measure up to 5 bar (from memory). It also has much better knock control than the PFC

I would definitely recommend it if you're chasing big power, there's more inputs and outputs you can use to watch AFR's, intake and exhaust temp and like a million other things to keep you engine nice and safe

the turbo itself shouldn't be a reason to ditch the powerfc....and with that turbo you probably won't max out a Z32 Afm. It really depends what your goals with your car are.

the tuning resolution on PFC is 20x20 not 16x16

the newer ECU's do have more features as the others have already mentioned so these should be considered for your future planning, but for what you currently have you don't need to change ECU yet.

I recently switched from PFC to haltech, the car runs the best it ever has,

For me the benefits are no MAF is great, the PFC random cough thing is gone, boost intergration is nice, having a few extra IO points is handy for running others stuff you might add and full data logging for diagnosis

Of course the skills/ability/attention to detail of the tuner will have a big impact on how the car runs.

Boost control will work with your existing solenoid you'll just need wire it up to the haltech and I'd run the external MAP sensor regardless of your desired boost level,I don't really like running a vacuum line back I to the cab

If I was to do it again and wasn't going for flex fuel I'd still ditch the PFC.

All in all the haltec is a good system. Good functions and options. Just be mindful that it has intermittent problems in processing the cas signal which lead to timing variations of up to 20 degrees. Not the only system that does this either. That's why a pfc is always a safe bet if all the extra functions aren't needed.

If you are curious to learn about what your car is doing, and what an ECU can do, and monitor shit and .. really just 'see' more then yeah.

Haltech's stuff is super easy to understand. The fact you can plug right into where the stock ECU is is just gravy.

On a slightly different note. If I wanted to replace a PFC on an RB26 and keep the AFM's what ECU would be recommended?

i don't understand why you'd want to do this? but the plug and play haltec will do it

    • Biggest thing is you're okay!   It sounds like between the accident, and the drive home, it was a pretty torturous trip again! On the bright side, you took the opportunity to enjoy the event more from the perspective of a spectator, than as an entrant!   Sad to see so much damage to the car. It really has taken a HUGE hit in the front end. If/when you choose to repair, hopefully the rails are straight (At least from shock tower backwards). Hopefully the extra cage coming through there has save most of the chassis rails, and HOPEFULLY saved the motor too. Best of luck when you eventually get motivated to start pulling it down to check it all out
    • Sounds more like what Brad said, that it's mainly transfer. What pad bed in procedure did you use, and did you replace/machine the rotors, or just swap pads?
    • The stutter is almost entirely in the pedal. I don't feel the brakes release and reapply as you would with ABS engaging but the pedal feels that way, without the brakes releasing. It only lasts for less than a second and the pedal is fine again. It's hard to explain, sorry.  I'll get under this weekend and just double check everything is tight. Fluid is at max where I left it.
    • What bedding in procedure did you use?   When you say stutter, what exactly do you mean? Like it feels like someone letting go of the brakes momentarily and regrabbing them again to get you to stop? Re-reading your post, and that is what it kind of makes me think you're explaining, like theres a little bit of a jolt, likely just as you're reaching a stop. I've only had this issue once. And if its caused by what caused mine, you will want to get the car up on stands again and check it over. Mine was a case of a caliper mounting bolt coming out and letting the caliper rotate on the other remaining bolt and gave play in a wheel as it came to a stop. But not every stop either!
    • Yeop... binned it   This will be a summary will not many pics atm and cbf  Fixed the samsonas - it was totally munched Put a new precision 7675 T4 on with proper split pulse mani Got to Sydney to get to car - drove to canberra to get racecar - drive back to sydney that night Next day all day at Plasmaman putting on new clamps cleaning some things up and adding another large engine oil cooler sitting at the rear above diffuser to keep things cooler Next day - Tuesday - on Dyno - killer wikid awesome pumped out really good numbers - more mid range and on lower boost levels Wednesday - first prac - all day again getting the suspension right - had to borrow front suspension again - out do a lap come in - out do a lap - in - what i had just couldnt handle the load at the more consistent higher speeds - got a lap in at the end of the day that was pretty reasonable  Put it this way that lap wouldve had me in 4th in Pro am for the whole event - with only 700 hp and used tyres Thurs first official prac day - lap out warm up - then entered a hotlap with above setting and 80% effort took corners 1,2,3 and into 4 car felt awesome -  rear came around out of nowhere bang into the wall near front on at whatever 140 kmph Done, over, gone Just one of those how did that happen apparently as all indications show nothing out of the ordinary Got to spend the rest of the time at the event like I hadnt done before - was actually Ok mainly as I had my family and my boy is 9 and got treated like a rockstar Long trip home, lost a trailer wheel in nowhere land, X5 airbag suspension gave up half way across nullabour and rode on bumps stops (its now completely fine) had to do a 19 hr drive day on day 3 as accommodation got screwed up so just had to keep driving till found a town with some Now to reassess - hopefully the motor and other things are OK but yet to be seen too. There is no easy fix there is no i'll just order that part and get it sent - we'll have a talk to people see what can happen and what the go is but at minimum its rebuild from scratch struts forward and alot of time effort and $ should and if I return and if but maybe/ when  I have the cage tied into the front strut towers - if I didnt have that things couldnt been worse you can say its just a front end but if you know what goes into these cars... you'll know what that actually means in reality   Car was very fast. Disappointing we just didnt get to show it Effort doesnt win you races though     Apparently this is motorsport !
