Finally!!! For so long the forums have shuned this ECU it's nice to finally see a forum sponsor support this Piggy back. How well would this piggy back work on a NA-T setup?

 

It'll work fine on an NA-T Setup. I recommend using an OBDII ECU in conjunction, but should work fine on OBDI. I don't have any maps for OBDI ecu right now, but if someone wants to be the first for me to tune it, hit me up.

 

Bryan,

You actually tuned my 1JZ with emanage when i first got it running for tx2k11. I have since switched to an Aristo ECU/harness. I havent had the funds to come see you again so ive been doing a very basic tune myself just pulling fuel out.

I do have a question though. The first time you tuned it you set the airflow output map, is there an advantage to doing that vs using the boost cut limiter and clamping the map voltage?

thanks,

Rich

 

Using the BCC, clamps the voltage at 4.2 volts. If I do that in the Airflow output map, it does the exact same thing. The boost cut limiter would be used when you are using the airflow output map on the MAF signal, AND using the boost cut limiter setting on the MAP signal. This is only good on US spec 2jzgte. Because your 1jz is MAP based, and we are modifying the MAP output, we can't use the boost cut limiter and have to do it in the map.

I have a question on this. I wired mine up and everything works fine, but when i run my ignition wires through the EMU it runs and drives fine, but if i try to launch it with my stock auto it dies instantly... any idea why? even if i dont have launch control engaged. as soon as I bypass the EMU I can bring it up to stall it again.

 

This is something I'd probably have to have in hand to diagnose. I've never seen this problem before. What factory ECU are you running? I can take a look at your map and see if there is anything abnormal. bryan@powerhouseracing.com

 

So on 2jz-gte (jmd spec), there is just a map "signal", no maf. U get fcd working adjusting airflow output volts? And u dont connect ultimates analog in and output wires?

Thank you, got answer in email.

i had an problem my my ultimate, ive tried again and again but it doesnt seem to make a differnce when i change my rev limit, also launch control. ive changed settings, check all the boxes and read the manual but it jsut doesnt seem to make a difference.

 

with the emange, is there a way to monitor when the ecu is in closed or open loop?

 

No, there isn't. You will need a scanner for that

 

ok so ive got 440cc injectors at the moment with a resistor box and there maxxed out for duty cycle, i have a few questions about changing to bigger ones:

. the new 750cc injectors are 11.7 ohms and the original 330cc injectors were 13.6 ohms, does this mean i will still need a resistor pack or is 11.7 considered high enough? (the manual doesnt state a spefic value it has to be over to not need a resistor pack)

.as for fueling at the moment everything is being trimmed individually at the injector adjustment map but with 750cc injectors i need to take out more fuel that what is possible (the map only allows for -80) so does this mean i would use the i/j before and after injector size in parameters and then tune the injector adjustment map from there?

thanks for the help!

 

No, you won't need a resistor pack. Correct on your second question. Remember, there are several different ways to achieve a good tune in EMU, so no way is necessarily the correct way. I may do it differently than you. That approach is the way most would do it.

 

Thanks for the reply mate, i haven't had a chance to change them yet but i thought about it some more, did some calculations and figured i should be able to individually trim the injectors just like the 440cc ones are at the moment. Will post results when in done. Thanks again

 

Let us know how it turns out!

as you can see its worked a charm, this isnt the final tune but just trimming i/j map by map sensor voltage x rpm ive been able to get it pretty damn close. oddly enough it idles (14.7) on the same duty cyle the old 440ccs did but all the rest of the map had to be leaned out.

 

Just noted that you have on your drop down menu Jspec/Euro on the same line, where Euro should be the same as US Spec.

Euro Supra uses 550cc injectors, AFM, has steel turbos, essentially the same as US Spec, but our ECU's dont seem to suffer from the OBD1 lean spot.

JDM is map based with 440cc injectors etc..

Just a note

 

That's great but im na-t so originally i have map, intake air temp sensor and 330cc injectors as its jdm not euro or us spec

 

Have you ever had anyone run injectors as big as 1250s on the EMU?

 

Yes, I have.

 

from what ive done with the unit i cant see why they wouldnt work. going for a dyno run tommorow but id say its going to hit 450hp quite easily

 

Hello everyone.
I'm having some trouble tuning with the emu.
I have a jdm 2jzgte non vvti from 147 aristo. 800cc denso drop in injectors, gt35 turbo, injector power supply set at a constant 14v to manage ij lag times. Still at 10 to 12 lb boost trying to dial in the tune before I increase boost.
Got the car to idle good after stock ecu had time to learn, at 14.7 with just injector scaling, but it runes extreamly rich in boost.afr 9's even with 20% fuel reduction. Tipping the throttle out of boost at low rpms and I get afr 10's. No change to accel map as yet.
I'm thinking that the stock ecu still needs to learn so I am just putting on the miles hoping it will get better.
Am I doing the right thing? Advise please.

 

I had to reset my ecu and let it drive for a few days without the emu, then hook it up and tune after teh fact to get any thing to stick correctly.

 

Hi guys, new member here and desperately hoping someone may be able to shed some light on the issues we are having.

So I bought the emanage ultimate back in December (also purchased genuine greddy loom to suit), I have only just gotten around to installing it, and my tuner (who is very experienced with EMU) can not get the car to run. Its a '98 tt vvti supra and we have nutted out all the usual problems and still nothing. I am hoping someone on here may have experienced the same problem... before we put the car back together and give up



We have:

Tried changing the jumper setting (8) to 12 volt - still not firing.

Tried to scope the signals at the igniter - still not firing

Checked the gauges on the 'dash' of the emanage software pulse when you crank the car over - still not firing

Tried all the different trigger types(we have rpm which is confirmed with the logger), so we have fuel but no spark.

Checked the pinouts in the harness

Bypassed the ignition setup and run it as a fuel only setup, which created random lights on the dash flicker on and off and also made it struggle to start, Idle high and run rich, all with no adjustment to the maps

We are at a total loss as where to go from here. Any assistance would be highly appreciated !

 

Is this harness compatible with a 1990 7mtge supra manual trans?

 

Hoping I can ressurect this thread and maybe get a hand with my EMU.

Currently hitting a cut 5krpm and I'm thinking its do with the boost cut limiter but I changed that from 4.28 to 4.3 and it started blowing intercooler pipes off and spiking to 25PSI so I've got it back at 4.28 now

I've got pics of Injector Adjustment Map and Ignition Maps. Little confused about them but can anyone tell me if these look to be correct?

Also included a pic of the data logger if that helps at all. I should Probly mention im running a Holset HX40 and 550cc injectors
