Hey guys I just installed an emu last week and I have been tuning it myself, anyway my AFM is maxing out pretty early (about 4500 rpm). The car pulls nicely in first and second but in third it hit some sort of fuel cut, I've clamped all the afm voltages at 5V but it still does it, it did it in second in the cold morning air as well. I turned the boost back down to ten and it's ok (was running 17-15) My question is, is this problem because of the afm? and will the map sensor sort me out?

Hey, can you post some info on your install ? Like what harness did you use (universal or n-4?) What jumpers did u move ? What firmware version do you run ? And how did your car behave on the first start up ? Drove like before ? Or have you encountered some problems with the install ?

Its probably your AFM maxing out. Iether a greddy map sensor or bigger AFM.

My car was running rather very badly before the install due to highflow turbo and bigger injectors. Car is running great now apart from the fuel cut. I've never played around with tuning a car before but thought I would give it ago and I have to say that the emanage software makes it rather easy.

I asked for a GTR harness but I was sent a universal harness so I just wired it in which wasn't too hard as it comes with ecu wire locations/descriptions (as in which wires are what and how they supposed to be connected to the ecu)

Jumpers that I changed were JP8 to 2-3 (12V) as per what URAS said and JP13 to 1-2 to change it from reading knock to water temp.

I downloaded firmware update 2.16 from here: http://www.mohdparts.com/emanage/

Only trouble I really had was getting a nice AFR on idle (and one wire that I stuffed up on install because I can't count to 4)

I've got S15 injectors and found the best setting to be 480cc with 0.06 lag time. This gave the smoothest idle and AFR of about 14.4-14.7

Heres a picture for anyone contemplating a wire in :laugh:

and a video of how it runs :(

One thing I would like to add to this is that fitting a bigger AFM is pointless with the ultimate as it converts the voltage outputs back to the stock AFM values. So effectively no matter how big the AFM you really have on the car is it will still have the same limits as the stock AFM.

Your only option is to wind back the boost until you have the map sensor on there.

I found this after data logging the AFM voltages on my Z32 to cure my fuel cut, since then I've gone back to a stock AFM to get the data sampling I need for the MAP sensor to work properly.

That does not sound right at all.

What settings do you have set for the AFM? VG30DETT? Or your engines AFM? (EG. RB25)???

I tried vg30dett and rb25 with a q45, z32 and rb25 air flow meters. The datalogs for all of the combinations showed the input voltages being appropriate for the air flow meter but the output voltages were all showing that the ultimate was converting the input voltage back to emulate the stock AFM voltages .

You need to vlamp it before 5V, email your map to me [email protected] and i will set the boost cut for you and email it back.

Still getting nowhere fast with my EMU install. Reset the jumpers to factory default and upgraded firmware to version 2.16. Wire swap done for crank/cam angle and rewired to select water temp and knock 2. Have selected RB25DET from parameter settings, started car but no better. Engine running very rough, feels like it is misfiring very badly.

Any suggestions as to what could be wrong? Put stock ecu back and car runs fine again, so must be EMU related.

had exact same problem. im sure the emu has good points. BUT...we tried to get it going for a good month. my mechanic and electrician could not get it going. we instead opted for the PFC. may i suggest u go for a plug in stand alone ecu. the emu has cost me nothing but time, money, sweat and tears.

PFC :down:

I installed and semi tuned the emanage myself with no problems and I only did this because my power fc broke nothings perfect!!

Very strange that some people manage to install these things with no problems and others have a nightmare. Would be useful if the ones who have had problems and resolved them could put together cause and solution table. Would help with problem solving without a doubt.

put it this way 99% of the EMU issues i fix on a day to day basis is because so-called experts fark it up.

PFC :)

see above.

for the money u pay u would sure hope it is perfect.

why buy second best :)

nothings perfect i tune twice as many PFC's as EMU's and i have had a fair few dodgy PFC's over the last 10 or so years.... maps all 0 etc. the problem is with EMU is it is up to the installer to fit it correctley and unfortunatley there are more monkeys with spaners and testlights than there are decent mech/autoelecs with a clue.

Have you got advice with regard to a "snagging list" to resolve my problem with the EMU? I would put money on it that it is something simple/obvious, but after hours working on it all objectivity has been lost apart from an irrational hatred of the damn thing. It looks like the easiest thing in the world to fit, which is why it is so bloody frustrating! :)

what is the serial number and there is a (D,E) letter code inside on the board... what is yours?

    • Depending on how long the car sat it is very possible for injectors to be stuck open or closed, I'd get them cleaned and flow tested. Other than that, obviously when the loom changes and the car doesn't start any more....the loom is suspect so some tracing / comparing may be required
    • Harness is for a s1 Rb25det, and it is engine and lower harness.  the old harness had broken off plugs and was in very rough condition/exposed wires and splices etc. it is not able to be put back on the car, I could visually inspect to see if they had rewired any pins on the ecu plug. The fuel pump definitly isn’t turning off it’s an external pump and very loud you can hear it. Will look at the other harness tonight, am also going to pull the fuel rail and watch the injectors spray, will update here with what I find. Pretty sure at this point it has to be something to do with injectors because car will fire up on starting fluid and cas is clicking the Injectors. Fuel pressure is steady 43psi 
    • Check the injectors flow evenly, and are actually flowing what you and the ECU think they should be flowing. If it's starting up on starter fluid, you have a fuel issue. Is it possible under cranking your fuel pump is turning off?   The harness you replaced, is that the whole engine harness? Do yourself a test, and drop the old harness on and plug it into the Z32 ECU. It's possible they've wired things different. From memory S1 to S2 is different in RB25 and you may have a wrong loom
    • I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off.
