Had a fair crack at fixing the ignition and fuel maps this morning.

Adjusted the scale on the A/F target, Ignition, and INJ1 to:

Start at 4000 rpm and finish at 7200 for rpm's

Start at 3.0V and finish at 5.0V for input voltage.

Still got a fuzzy bit in the ignition timing around 6000 rpm's where the timing goes from + to - with only one row of 0's seperating them.

Might have to space it out a bit further apart with the scale changer.

Heres a pic of my new datalog:

Still some work to do, but the AFR's are looking really nice now. Power delivery is very much improved.

what is the serial number on the back?

hey got mad082 to help he changes 1 and 6 around and it works okay still has a small miss. what should pulse rate be??? there 550 cc inj

Could you please tell me exactly what was swapped around to fix the miss you said you had on your injectors UCD15R33?

You said someone changed 1 and 6 around? You mean removed and swapped injectors around or whats the go?

Just curious what fixed it for you because I had a severe miss with one of the injectors I was using.

Mad082- he swaped my injector 1 and 6 and resealed them using grease cause number 6 wasnot sealing. But now I need lag time cause it has a miss when u add loan and a/f ratio is very lean.

Hello

I want to install the e-manage ultimate in my r33 gts25t spec 2 -97

What do I need more than this ?

https://www.rhdjapan.com/jdm/TRUST-E-Manage...c-Harness-24517

for ecr33

and the Ecu https://www.rhdjapan.com/jdm/TRUST-E-Manage...Main-Unit-18517

Does I need any moore parts ?

Is it just bolt on and then I can take my car out for a ride ?

I want to drive with a Map sensor instead of the afm is that possible and what do I need for that ?

Best regards

Simon from Sweden ( sorry if you don´t understand)

Your going to need the pressure sensor as well as the pressure sensor harness. Also get a usb cable to connect to pc.

It is just bolt on and go, although you need to connect it to a laptop or pc to configure it before you start it the first time. This is to tell the emanage what type of car its connected to and what it has that isnt standard. Once its configured it will still be outputting the exact same ignition and fuel signals as the standard ecu signal thats coming in. The maps need to be adjusted on a laptop via a usb cable to make any changes to the ignition or fuel ect.

When you have done this, you will need to create a map BEFORE connecting up the map sensor and removing the air flow meter. This is explained on this thread a few pages back.

hey im working on getting a new interface for the ultimate up and running, can someone post up a ultimate datalog? or email me one NOW? i left all my shite at home :( and need it it kinda urgent so they can decipher it.

This might be a crazy idea, and I'd say someone has tried it before:

To upgrade injectors on my r33, leave standard FPR, Injectors and rail.

Buy (1) 900 to 1000 cc top feed high impedance injector. $80

Using the emanages extra injector driver chanel, weld a bung into the intake pipe before the throttle plate for the injector.

Make up a hose from the rail to the injector and bring it into operation at around 4000 rpm.

6 * 380cc = 2280

6 * 555cc = 3330

6 * 380cc + 1000cc = 3280

Any thoughts?? :rofl:

Cheers for the advice really appreciate it, think I might go for the ultimate, the modifying process is a never ending one as i'm sure you know. So better to be prepared.

I had an Ultimate in my R33 GTS-t and it could never be tuned right.

It was boost spiking at certain levels(between 2500 & 4000) despite proper tuning!

Ripped it out and popped in a Power FC!

Best thing i ever did.

tuned or installed incorrectley 1000000%

r33 is a piece of piss and works fine... done around 30 now.

Sorry to dig up this post, but I have a question about the EMU that has not been addressed at all in this thread.

Will the rev limiter cut function work with the RB20/25/26 ECU's? I have tried in vain to raise the rev limit of my S1.5 RB25DET using this feature. No matter what I set the TP%, cut time, hold & limit values, and injector duty cycle times to, the engine will not rev past 7000 rpm. I am using the P&P N-4 harness with my EMU, and have repinned it accordingly.

If anyone out there has gotten this to work, please share what you've done. Thanks!

BTW, I am in the U.S. and have the 25 squeezed into my S14a (will link pix if requested) :)

URAS, I also PM'd you about this and a few other things but have not heard back. If you have some time I'd really appreciate a response.

sorry i get bombarded with pm's so i miss a few :blush: can you email me a datalog of the car hitting rev limit say in 3rd? and also your map, i will then try figure it out and send it back ASAP. i will also explain how to do it based on your info :)

    • It was a great, but typical track day, and some VB was ingested at the night time debrief 🤪
    • And so, to round this out, I couldn't be happier to confirm @MBS206 has decided to buy the car. He drove down from sunny QLD with a trailer last week and it is off to its new home today. I'll let Matt confirm on next steps but I understand broadly that the plan is to leave it pretty much as is, and just get some quality wheel time with a nicely balanced car that is pretty much track ready. There are a few a jobs still to be done first but nothing too major and I think its a very smart buy Dinner last night at the Paragon with a round of VBs (mostly) for Neil
    • Well, 50 pages and the end of a chapter for this car. We took it out for a shakedown at Wakie yesterday, and everything went well. There were a couple of niggles: - Oil cooler fitting leak - tightened, cleaned, stopped leaking - Radiator cap overflow fitting was leaking....Mark called it, the overflow fitting was threaded in and not tight....tightened, tested and held pressure - Small oil leak at the rear of the block, probably the turbo oil feed - too hot to get at it comfortably but probably just needs to be nipped up - leak at the driver's side rear brake line where it meets the hardline. Fitting wasn't loose, so Matt backed it off and back on, no further leaks - there's also a leak somewhere on the top of the fuel tank, maybe that cross over fuel line - that was has been left to fix when its on a hoist Otherwise than those niggles the car went great, turned great and stopped great so it was a very successful day out. I'm always really nervous when a car first hits the track after a long break, especially with a brand new engine as well but it was great. VID-20251011-WA0007.mp4  Big thanks to @The Bogan who dropped by and helped out, @MBS206 and my nephew Lachlan the apprentice.  Neil's wife Mel also surprised the hell out of all of us by dropping by; she's up in Tamworth these days but was travelling to Melbourne so had plausible deniability for turning up at the garage, it was great to see her but also obviously a bit sad all round.

    • Unsolicited advice? Keep the engine as close to stock as you can. Nothing wrong with adding some boost and making a little more power, but given where you are, you really don't want to try to make it into a monster. I can't imagine the roads are up to it, and the lack of locla support when it grenades will be a ball ache. FWIW, If there is a dyno around that you can access, then brand new injectors are a good idea, which will lead you to (at least) putting a Nistune in it, which will allow you to put an R35 AFM on it, all of which will make it possible to make it much much nicer to drive and live with.
