Hello from France ;)

I just change my turbo on my forged RB3025.
I had a GTX3071R (too small and making too much EGTs)
And i'm puting a GTX3582R AR1.06.

Car is running good and pulls good for these 1.25 bar i'm starting with.

But when there is a good load (like in third or fourth gear) the fuel is cutted suddenly @ 6200rpm and if I stay WOT, the rev stabilises @ around 5800rpm.
I Can hit the 7000rpm limiter only if I'm in neutral or in first gear.

I suspect it to be a ECU tuning stuff on my nistune. So I let my base tune and 2 logs (first in tuner mode, second in stream mode)

NB, when converting to RB30, It was necessary to unplug the MAP sensor unless eratic working under 2000rpm.

(tuner mode with TPload shown)

(stream mode without TPload shown)

Hoping someone could help me ! ;)

I never had ti unplug the map sensor to get mine to run nicely.

Email nistune with your issue. Mat will be able to point you ib the right direction.

I assume you have set up the max tp settings etc.

I couldn't have a complete answer because mat had some personnal issues.

So put some more elements for you to see.
Here is one log attached.
At this moment I'm 4,66V on my Z32 MAF. (I tried yesterday with a ford lightning maf 700hp, and I'm 5,1V at this same 6000rpm when it cuts.)

    • The speedo's can be very conservative, when my Mazda NC MX5 speedo is showing 118kph, the GPS, and a calibrated radar.... cop mate.....hits me at around 110kph +/- 1 or 2 kph, and that is on a 215/45 17, stock tyres size is 205/45 17 as well, so weirdly conservative with stock tyre size When my Commodore speedo red 116kph GPS had me at 110kph After doing some offset and clearance measurements to see what can fit the NC on 17x8 +40, without guard rolling or rubbing anything at my current ride height, I've decided that when my tyres are toast, I'm going to fit 225/45 17 and see where that gets me IRT actual speed of my speedo and GPS/radar From the online calculator I should be still be doing around 5kph under an actual 110kph when the speedo is showing 110kph My ADHD requires that when I'm doing 110kph on the speedo, that the actual road speed is actually really close to that, and not alot slower And going from 205 to 225 still keeps the car within the %/mm allowable in the NSW vehicle rules and regulations, which is nice, as long as I'm looking at the latest version that is.....LOL https://www.nsw.gov.au/sites/default/files/2021-02/RMS-13.464-Light-vehicle-modifications-Vehicle-Standards-Information-No-6-November-2013.pdf
    • 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?
    • @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?
