Nengun site so I'm not sure who/what translated it. Would be good to get a hold of some complete info. I had a look around for V specific info the other day to see if this was a feature on all F-CON models but didn't turn up anything.

its always goign to take a second or so to change gears on full throttle changes.. that's the way the nissan gearbox is

if you want to change that, then a shift kit is a great investment :)

If your are interested here is a xls file of raw data and graphs from Newkleers LCD Box and NissanDataScan software that I did the other day trying to sort out some problems.

It shows the timing cut and change from first to second at near 7000RPM.

The Auto has been modded with a firmer shift plate and Kevlar clutches, 2800RPM stall etc.

BTW this is with ECU ERROR 34 - Knock Sensor showing all the time.

Can anyone tell me the implications of this error on the ECU maps and general operation of the engine under this fault condition?

Sorry I cant give you a definite answer on this, but logic would say that:

Knock sensor not working = ECU assumes engine knocking (just to be safe and avoid a waranty claim)

therefore retard some timing.

HOWEVER - if you have set the timing when this was faulty you may have already compensated for the retard, but removed the safety measure on the rare occasion you get bad fuel or heat soak in the intercooler.

Well I have bought most of the parts and have gone with a PFC. I would have gone with an F-CON but no one in Vic tunes them. So I should have all the parts within a week or two but might wait til Jan to do the install. Depends on when I have a bit more cash to get the spare turbo rebuilt and pay for some of the install and tune. I'll be installing as much of it myself as possible but lets face it, I'm an IT tech not a mechanic. I can do a service, change plugs and coils but fuel pump and injectors and I have visions of exploding cars.

*edit...is there a seperate ecu for the auto transmission? or is it all inside the engine ecu?(front left of passenger seat)

for r32gts-t's

not sure on the 32's but the 33 has a seperate ecu in the right kick panel for thr auto.

Glad I found this thread... I will add my Datsun 120Y that has a RB20DET auto

Engine has

20thou forgies

Walbro + Bosch 044 & surge tank

GTR ingectors

Stock AFM just before the throttle body

3" exhaust

Garrett GT35R 0.63 exhaust

38mm Turbonetics external gate

Auto has

MV shift kit

MV manual shift controller

B&M pro ratchet shifter

4200 stall converter

trans cooler

185 kw

I could only find my 13.1 @ 113 timeslip from yesterday but it has done a 12.9 @ 113.

Best 60 foot is a 2.25

I use 205x50x16 Toyo R1-R and a 3.7 lsd diff.

I have been told I have the incorrect type of muffler fitted and i need a straight through design.... Damn restrictive V8 muffs.

Well after finally getting a half decent converter in, last night i did a 11.89 @ 112mph.... 1.71 60 foot time.

I will upload the time slip in the next couple of days :)

Here is a pic ..

Update, the new fuel system netted a massive 157rwkw!

We lost AFR readings at 5000rpm...they dropped off way past 10:1

The new turbo/bleed valve combo won't hold boost either, this should all be fixed in the next 2 weeks with some nice figures to attach :wave:

    • CTIS (Central Tire Inflation System) has existed since the 80's. I'm looking into buying a Hummer H1 and they generally included it. 
    • My idle is set at 950rpm though - Moving the timing around 20 degrees is not really what I'd call a calm idle. That said... neither is chop, by definition. The LS ECU likes to adjust timing to hold idle as opposed to air. It'd work, but generally speaking there'd be a discrepancy in the base idle and the IACV would want to move the timing around anyway to maintain said idle. I think I'm just going to keep the timing steady anyway. Preserve my engine mounts.  My aircon is now officially regassed. As the guy was reversing I noticed my reverse lights do not operate, along with my reverse cam. This is a bit distressing, because 100% of guides talk about which wire to connect to backup cams as "the goes with the [other color] wire". Often when doing conversions. Unfortunately the R34 colour wires aren't documented Unfortunately I had a T56 Magnum gearbox with it's reverse switch, which also isn't documented. Unfortunately there's definitely not documentation for people with both of these in the one car. Unfortunately I forgot. After many hours of this, I have a reverse cam and reverse lights again. The wire going through the trans tunnel to the reverse switch had broken. Upon inspection, it looks like this one wire had about 7 spade terminals and extensions in it.. for reasons I cannot possibly comprehend. I also spent the 750 hours required to clean up the wiring behind my head unit which now looks like this: This is a monumental improvement relative to what used to be there WRT triple gauges, head unit, traction control, wideband controller, and whatever the f**k OEM stuff still exists there in various states of connectivity/needed. Next step is to check in at the Exhaust shop to see/confirm how much clearance I have, to decide what mid mufflers or 'resonators' (which are just straight through, narrower mufflers) I can add and hopefully cut out a lot of exhaust leaks, pinhole, v-band or otherwise. But first step will be to 'take a look' before the next step.
    • Fark the AFM card and Nistune, Haltech Nexus S3, DBW, cruise control, flex fuel, dis dat.  
    • It's most likely the bolt/bush where the cover bolts back wore and allowed cover to move forward.
    • Still haven't put the injectors and R35 AFM in so we can tune the bloody thing for the HG highflow it got mid last year! I think I can forecast the upgrade path to a bigger twin scroll, external gate, Haltech, flex setup, Samsonas, dis dat, etc will be .... a while away!
