Hey ppls.

Well, the time has finally come.

I've had a PowerFC sitting in my drawer at work for well over 9 months, and I've had a PowerFC boost control kit also sitting in my desk drawer for about 3 months.

Today, she's up on the roller to give it her all.

Was spurred into action by the good reviews of Genesis and the quite reasonable prices offered. Also, talking to Craig the tuner, he seems to know his stuff inside-out.

He used to tune for BGT/Hypertech and did 99% of the tuning on the Hypertech cars.

Anyway, I've attached a power run that was done yesterday on the dyno where it's being tuned so that I can get a good comparison.

One is boost again AFR and the other, Power against AFR.

Bass is a little excited today as you can imagine.

I'll put the new charts up as soon as I have them

Okay,

At 7pm on Friday night, I made 200.4 rwkw from my baby.

I'm posting charts as soon as they are scanned.

Will also post a full report of the feel of the car sometime today.

Hey ppls.

Well, please see below the dyno charts of my car making a bee's winky over 200 rwkW

Dyno was at Hypertech Automotive.

Time, was about 7pm last Friday afternoon.

I'm quite happy with the result and apparently, this dyno would read slightly higher in Shootout, but a dyno is just a tool anyway.

I'll be taking it down the strip as soon as I get a chance and I'll be aiming to get into the 12's

Craig from Genesis spent most of the time of the tune in the workshop putting in a base tune, then drove to the dyno. First Dyno, F1 Performance, left before we got there, even though they were booked. Second Dyno, Hypertech, we drove straight onto. They have a very very nice dedicated dyno room, all sound proofed and stuff. 4WD and the works. Drool.

Anyway, pulled probably 10-15 runs total, tuned in some lean cruise and that was that.

Car now idles much better (was a bit rough before due to the flywheel) and pulls cleanly. Has an urgency to it now and comes on boost and stays on boost like a champ.

I had the actuator and boost control kit fitted and it holds the 11psi no problem.

AFM is within a couple of percent of maxed out at about 5500rpm, so it's a new one of them for any more increases in grunt.

So, all in all I'm a happy chappy.

Nice result Bass. :D

Tell me the AFR graph - http://www.skylinesaustralia.com/forums/at...achmentid=26047

Is that the cruise mixtures before and after? After being the 14.?

Keep us updated with fuel economy figures. :D

I'm keen to see how your 60ft goes with all that extra wheel spinning power. :(

      Take the value it measured as, and pick the closest range available that is above the reading on the screen.   Also, no point just testing the coils. Read what has been said again. You need to test all your wiring, everything.

      Does the scanner do all the CUs in the car, or only the ECU?

      R34 N/a And R34 Turbo (gtt) Transmission.. Uh, Problem.

      By albyz34gt · Posted

      @666DAN sorry to bring you and old thread.     I've got my de+t done and it's all running great other than 1 small issue.    Car has remained auto with the na auto and tcm, I've used a stagea ecu with. NIstune board and everything is great other than my gear selection on the dash. It illuminates park, reverse, neutral, 3rd and 2nd when selected . But nothing when in  drive or what gear your in when you pop it into tiptronic. I'm sure there is maybe 1 wire in the ecu plug I need to move to rectify this. Do ya have any ideas?     Cheers man

      Well I recently changed my rear axles and was thinking if I bumped anything, I have been driving the car for a while now though... But it has been raining today so everything is wet under the wheel arches. Brakes feel fine and can't hear any of the metal screamers, I had a squeak coming from one of the handbrake drums but that seems to have gone away a while ago. I was going down a hill when it lit up and I did feel the abs bite for a second and question why it did it?

      ECU sees many times the speed than speedo does (R34 swap)

      By GTSBoy · Posted

      Correct. Um. I dunno. I haven't cared enough about the way that the NA cars work to know for sure. But..... The 33/34 turbo manual cars have an electronic speed sensor in the gearbox that outputs a +/- (ie, sawtooth AC) voltage signal. That is connected to the speedo. The speedo then outputs a 0-5v square wave (ie, PWM) signal that the ECU (and any other CU on the bus) sees. The speed sensor is NOT directly connected to the ECU. So here's the problem. Your new ECU expects to see the PWM signal, but must somehow be getting a direct signal from the diff speed sensor. Which would suggest that the wiring of the NA car is not the same as the turbo cars. I think you will need to spend some time with (hopefully the wiring diagram for the car) and a multimeter to see what is connected to what. Then, presuming I am correct**, you would then want to separate the ECU speed signal input from the rest of the car's wiring, and probably either buy a speed signal converter, or build one using an arduino (or similar). That would take in the speed sensor signal and output a scaled (and suitably rearranged) signal for the ECU. ** We shouldn't presume that I am correct here, because there might be something else crazy going on. I don't think you could convert the speedo to be fed from the gearbox sensor, because the pulse rate from that sensor is probably different to the diff sensor and then the speedo would read wrongly. And this also wouldn't fix the ECU's problem either, because the ECU doesn't want to see the gearbox signal direct either (assuming that they are all on the same wiring, for some odd NA related reason, see above caveat!) Does this help? Probably not. Can you make it work? Almost certainly. With the above work. You should buy a handheld oscilloscope from Aliexpress so that you can view these signals directly. Connect up the probes and drive the car. Show photos of the screen when drving at known speeds and connected to different places, and we'll see what we can learn about it.
