^ that's exactly what i was going to point out.

its the higher boost that is making more power, and all the E85 is doing is alowing more boost to be run without detonation.

I think my GTR could make near that if it were able to hold 25psi boost, but it seems to peak at 25 then trail off to 20psi

Anyway's, will see what it does on the dyno this weekend

Are you running standard or aftermarket actuator / wastegate springs? Judging by Donnans HPI article, youd see some good results with a stiffer spring!

I've got 14psi actuators from memory? i remember when i had them fitted to the std motor the tuner had to just run wastegate tension because when they were plumbed in boost would hit 18psi.

i've got an Turbosmart E-Boost Street, so it should be able to control boost well enough. might just need some fiddling with the settings to control the wastegates better?

shouldn't i just be able to have the wastegates tightened to hold more boost?

i think they're adjustable, they have a threaded rod which looks like you can tighten of loosen to adjust when the wastegate cracks open.

yeh go speak to jason at mtq.

my external gate hold 20psi flat, put 25psi through it and it bleeds back to 20psi, fitting a stiffer spring will mean boost holds and it bosst will come on earlier too :)

    • After using a protractor for an actually accurate assessment of what is required,  and by NOT using my uncalibrated eyeball I worked out I need a 25° silicone bend from the TB ro the MAF, but, my choice was either a 30° or a 23° (23° is a weird spec), so I grabbed the 23° one from Raceworks I also grabbed 1mtr of 3" straight from Just Jap, I needed 350mm, but they only had 300mm, or 1mtr lengths....meh Also ordered a 1/2" hose bulkhead fitting from fleabay, this has a smoothish mushroom looking head (they are designed for below the water line of boats) that will fit inside the bend, the hose bit and threaded bit looks to long, but nothing that a hacksaw cannot fix if required, the hose will then just get jamed on the threaded bit up to the retaining nut Fingers crossed and the unsightly amount of hose clamps will be reduced down to 4 once all the parts arrive 
    • Oil change does not trigger code 21. Code 21 is for coilpacks primary side connection. You can try to clear the code with a battery disconnect, hold down the brake pedal to drain capacitors through the brake lights with the ignition on for 10-15 seconds before you reconnect the battery. I have seen R35 coil conversion permanently cause this code with no ill effects so it might be the resistance it wants to see isn't quite right on one or more coilpacks. Could be inside the ECU, could be the harness, could be a coil. You can test it all if you want or just ignore until the car actually starts misfiring.
    • I forgot you have a Nistune ECU. Use Nistune to do all the tests I mentioned instead of faffing with 30+ year old electrical connectors. You can read MAF volts off that too, there are reference values in the service manual to tell you roughly what it should be in different conditions.
    • No. I think it might be the AFM. Hence the use of the terms "swaptronics", which implies the use of swapping out electronics for the purpose of diagnosis. It's about the only way to prove that a small/niggling/whatever problem with an AFM or a CAS or similar is actually caused by that AFM/CAS/whatever. A known good item swapped in that still gives the same problem is likely to be caused somewhere else. They're all the same. Spraying AFMs with cleaner is an each way bet between cleaning it and f**king it.
    • Oh wow! This might actually work amazingly. Do you know the ratio of the diff? I was told the only thing you need to make sure of is if the front & rear diff ratios are the same. Ours is a 4.083 Thanks!
