I've just got a modified standard ECU put in my car.

I've been umming and ahhing about the Greddy emanage and other things but the opportunity to put this in just came up so I went for it.

It's got the limiters taken off it and I dunno what else. Details are a bit sketchy. So far I have noticed that the power delivery is so much smoother than before. I think it's because before the standard ECU was constantly making corrections due to the higher boost.

I would say that the seatofthepants-o-meter is registering a 10-15 kw gain which isn't a lot but the new smoothness means that it feels, and should be, faster. When you floor it in 2nd (or any other gear for that matter but I want to keep my license) you are not sitting at peak power the whole time. By getting rid of the tiny little hesitations as the standard ECU corrected and re-corrected it gets to redline faster. I've hit the rev limiter in 1st gear twice now by accident which I normally never do. (bad me)

So boost cut is gone, speed cut is gone (yay for the Eastern Creek straight) and it only took about half an hour to learn my driving habits and give the extra power over.

Beauty is that the Nissan consult can still be plugged into it and the trannie has no issues whatsoever. I presume I'm going to blow up my diff now.

how much did it cost u to get the modified ecu?

where from?

Abo Bob,

you legend, I have been doing lots of research and I couldn't get a straight answer on whether or not it would really work, it seemed the only other option is a SAFC2 which seems outdated now.

What other mods do you have, what boost were you and are you running now?

I have FMIC, 3" exhaust and dump pipe, pod filter, boost at just under 1 bar (14/15psi). I am getting a bit over 150rwkw which seems low due to mods but I seem to be running very rich, I am told that the emanage (excluding ignition harness which I am told won't work on the autos) should give 30-40rwkw if I run 17/18psi when the boost cut is changed? What are your thoughts? Do the R34 turbo's cope with this amount of boost? or does the nylon wheel melt?

Also, as AFRO asked, what did it set you back, and where did you get it done.

Cheers

[Abo Bob]

Cost me a grand as an exchange from Powerplay but it's a bit of a one off at the moment. Give them a call in a few weeks or about a month and mention my car (they know it).

Hunter - That does seem low. I had 162 with less boost. I have Nismo panel filter, CES split dump/front pipe, 3" cat, Fujitsubo cat back which is fairly quiet and an AVC-R for boost.

Just went out for a blat and turned the boost up to 1 bar just to see. Seemed to cope fine although the turbo seemed to be surging a little. I think that's because I don't know how to adjust the boost duty cycle on the AVC-R.

If you consistantly run 1 bar something in your turbo will let go so I'd stick to 0.85 if I were you.

[AFRO]

ok,, umm i dunno if this is meant to be correct or not,,

but i got mine dynoed ,, and i was getting 177rwkw, and mine is stock!

except exhaust,,,, standard boost and all,, even down to the factory air filter,,

but it was running a bit crap lately and ecu has error's 17 & 46,, might get it dynoed again,, to make sure everything is running ok,,

it was dynoed in shootout mode,,

edit:- mine is manual,,

The auto does lose a bit of power.

[hunter1234]

Abo Bob,

Did you get all the harnesses put in, ie ignition etc... or just the fuel component? I am still considering getting the whole emanage kit and I am assured by Advan (the Trust distributor) that all the components work with the 34 auto and the coil frying problem has been addressed with the latest sw revision.

Now that you have been running with it for a little while is it still running well, is the auto box coping ok? Feeling any faster? I am told one would expect around 40-50 rwkw, what do you think?

Cheers

[ed]

40-50rwkw increase?

I'd like to see that with a tuned ECU and no other mods!

I can't see it happening though

[Abo Bob]

I don't have the emanage. Advan need to get their story straight. I've been told by one of them there that it will work fine but that you can't use the ignition harness and by another that he "doesn't recommend putting it in there at all."

I have a modified standard ecu.

So far I would say that I'm a little concerned about the auto's power handling abilities. The flaring that I used to get between 1st and 2nd gear when cold only now seems to need to more warming up to work properly. If I redline it however, it drops timing or something, does a little fart out the back and kicks into 2nd beautifully.

I'm going to look into changing my fluid.

Good to hear there is something else out there....the second I get another e-manage ignition harness though I'll put the diodes in and give you guys the details....hoping to get a harness next week...unless one of you guys has one laying around you could sell to me?

Yeah the flaring is easily sorted by a good warm-up....once the car hits temp you don't ever get it.

[Abo Bob]

How is your diff going Dan. Mine is a bit average when very warm.

There are 2 problems with the EManage in autos, the first is the coil frying problem, but that happens to manuals as well. The real problem is it removes the ECU control over ignition on gearchanges, this means you end up with very jerky gearchanges. Plus, with no power cut, the gearbox will wear much faster. Simplkistically this is because the EManage has no gearshift logic.

I believe there may be a cure for problem #1, but I don't see anyway for problem #2 to be overcome with the current logic.

So I am looking forward to your results.

[666DAN]

My diff is fine......seems to be still going great-guns after 130,000ks of driving fun

I'm hoping that I'll have some useful info for you guys then...as long as I get all the credit haha jokes

how did they do it abo bob? modified standard ecu for skylines. thought that was impossible as no one worked out how to do it properly or am i thinking of r33 gtst when it comes to chipping the ecu?? SydneyKid, help.

if not looks like il be having a chat to powerplay in the not to distant future...

probably a daughterboard.

the japs have been doing it for ages for the 34.

yeah the ecu requires a new chip, the in the 32s you can just download to the existing eprom but the 33 and 34s require a seperate chip.

[Abo Bob]

I tell you what... My first tank of fuel with the new ECU has gotten me about 150 k's so far with about a quarter to go. Hmm.

[Duncan]

hahahaha someone has been boosting a lot trying out the new puter.....

just run it on a dyno, check the AF ratios.

[666DAN]

Harness will be here next Wednesday, so should have some info for you guys over the weekend......it's one small step for man, one giant leap for autos,e-manage & ignition

[Abo Bob]

Well I just did a dyno run to find out the following:

1. 189.4 rwkw at 0.8 bar which is up from 162 rwkw at 0.85 bar before the ECU.

2. I'm not sure how to read air fuel ratios. It's between 10.9 and 11.65. Which is leaner?
