I have a couple of odd questions. I have my emanage Ultimate installed finally. I have some question about running it along with a SAFC as well as the correct setting for the Injectors. So to start. I can occasionally get the car to actually start up and run, both with and without the SAFC connected. Without the SAFC it runs pig rich and of course throws an error saying it's not getting the Airflow readings. With the SAFC installed it occasionally cranks over and starts up and it runs decently but not consistently, so obviosly there's an issue. My question is 1 Does anyone envision there being a problem with leaving the SAFC hooked up with no corrections being entered? I'd like to leave it that way for a while and use it as a knock sensor for easy visual feedback as well leaving it for when i pull the EU in and out. My 2nd question...is what should the Injector size be entered as? I have a z32 MAF and 550 CC infectors. I've tried playing with different injector sizes but none quite work out and provide a consistent start and run. This was a little long but let me know what you think.

Thanks!

 

How have you actually done the wiring? I take it you've got both the EU and the SAFC tapped on the MAF line (as opposed to intercepting it with the EU?) I wouldn't recommend running both on the MAF line. Furthermore there is a knock input on the EU, not sure why you'd want to run both? The EU is vastly better than the SAFC anyways...

As for fuel control, I wouldn't bother with the injector sizing on the EU. All that does is scale whatever corrections you make in the INJ maps. If you've got zeroes (ie no corrections) then the scaling won't matter. If you need to pull fuel, do it directly via pulse width/DC in the INJ map, or via the airflow adjustment map. See the writeup in my sig for tons of EU info.

Initial cranking will always be a bit glitchy with large injectors and the EU, but once it's turned over a couple times you should be able to dial it in with airflow or fuel adjustments, use the water temp correction map(s) if needed also.

 

THe SAFC i did not install myself but it looks to be intercepted on the SAFC i think that's the the only way to run it since it's basically a maf hack right? furthermore when i disconnect the SAFC and crank it the EU is not fed a Maf signal at all and throws warning messages. I have a harness like the one you built for yours and the MAF signal is intercepted on it. I've definitely got your write up already it's invaluable. I guess i will completely pull the SAFC out and work from the injector/fuel map and see if i can get it going that way.

 

It might take a bit of messing to get things dialed in but I'd recommend doing that. Once the SAFC is out and the only thing on the MAF line is the EU then you'll be able to start from a clean base. Or if you're leaving the SAFC in for knock, at least eliminate it from any MAF signal for sure.

So once the EU is flying solo I'd probably start by removing some MAF signal at warm idle to get the fuel down (and pull additional amounts for cold conditions on the water temp map (not the main map) if you need to). Once you have that sorted out reasonably well then you can start correcting the other areas. Feel free to email/PM me if you need to.

 

Success, the car is up and running on the EU. It looks like the REV D Emanage still causes that 0201 check engine light so i'll need to add resistors to it. Now the oh so fun tuning part...

I'll PM you I have a few question about somethings relating to the sensors as well. Thanks!

 

NP.

Yep even version E still causes it... except for one instance (I have no idea why), I've never heard of an A32 or A33 ECU not throwing the CEL without the resistors.

 

Good to hear you are finally get this car properly tuned!

 

Yeah, too bad it's taking so long to get it done

 

Bump, I'm curious, do any turbo or supercharged guys have a map i can take a look at? I don't want to use it,because obviously they'll be different i just want to get a better idea of what sort of numbers you guys put in and what maps you have used.

I've almost go it starting up perfectly but there's an annoying warm start issue that just won't go away...
