M35 Vq25det Greddy Ultimate Ecu Wiring Install

[BoostdR]

Hi All,

As promised here is a copy of my install notes. Water temp is external as I found the OEM sensor signal to skew when tapped.

Innovate LC-2 wide band is used for narrow band emulation and EMU autotune

Vehicle setup: VQ25DE OR VQ35DE

Speed pulse: TBA(think it was 16pulse, 21% correction)

If someone has spare time and wants to put this info in a neat spreadsheet please go ahead.

Matt

just received boost sersor/harness and A/F harness today, and EMU is on the way

from the EMU manual, i think you can either connect knock sensor or water temp sensor for No.32?

[BoostdR]

I have the knock sensor connected however there is no pickup in the logs, even when I can hear the knock. Doesn't look like the EMU is compatible with the M35 sensor. Happy to be corrected

Which MAP sensor did you get? The Chinese version is very noisy on boost. I'll be changing mine as I run MAFLESS

No.71 on ECU pin is for knock sensor but i never try to test the signal.

i got genuine greddy map sensor from Japan with all other genuine harness, not chinese one.

Nice. I'll be interested to see the log for the map sensor to see how stable it is on boost. I tee'd off the first fuel pressure reg feed for the smoothest signal. Still crap with my Chinese MAP. Moves up and down 4-6psi at 26psi.

Yes I have pin 71 for the knock sensor connected. Doesn't work for me. Tried most frequencies from 6-7khz

Here are the speed settings

EMU is a long term project for me, haven't bought wideband AF sensor and big injectors. LOL

i have no idea for the knock sensor signal

The stock knock sensor works well with a set of knock ears.

[BoostdR]

Roger that. Oh and thanks Scotty for helping out mike with an AFM

Rev limiter moved to 7500. You need to change the rev limiter unit setting to duration whilst leaving the injection unit on % duty cycle so the autotune still works.

No more bouncing of the limiter when it doesn't want to change from first to second )

Bless you Matt- BoostdR. So helpful!

[BoostdR]

Welcome. If anyone needs a emanage ultimate I have a spare one which also has the ignition daughter board which stops the check engine light.

[Reaperblitz]

Does CEL pop up with an emanage hooked up..?

Is the daughter board separate normally?

Also- what did you use your analogue output for?

If we tapped that into the throttle position, would it be possible to open loop that so the brake cut mod wouldn't be required?

Just throwing ideas.

for ignition daughter board, it is separate board as an optional part for EMU, to avoid ignition CEL.

i have EMU and daughter board, i am wondering if you can share some picture that how to plug the daughter board into EMU.

What's the go with the daughter board? I haven't heard of that before! Costs?

I picked up an EMU a few years ago, I found it again only recently - I really need to get around to getting it installed and finally tuned! Have you fitted one to anyone elses apart from yours? Would you like to?

just a small patch board for EMU, RRP 1300YEN, quite cheap.

Oh brilliant, so its really just a tiny expansion board that clips straight on to the EMU. Are you running one Matt, or are you content with a constant CEL?

[BoostdR]

I have 330ohmn resistors wired from each coil input to earth. Does the same thing as the daughter board. I have a CEL from the brake cut mod but none for ignition.

Yes. Also fitted one to a mates Stag. I'm pretty busy these days.

What's your jumper settings if you don't mind me asking? Also out of curiosity did you guys use a harness or just splice tap straight to the unit. I have a uni-harness cable that's like 2 metres that I'm cutting down..
