Question: If I want to have control of ignition timing and injector while not boosting, (as well as when in boost) can it be done with an Emanage ULT? I don't think so but I don't know. If I just I extend the operating range of my existing inj and ign maps, they will surely be way too coarse. Seems like I would need to be able to call up two sets of maps, real-time.
Otherwise could I do this with an AEM 1052? If so, is it one big injector map and one ign map, or are their two maps for each (4 maps total)?

-thanks

 

Yes - you can with the ULT

 

on ems you have a vacuum and positive pressure on the chart. with fuel and ignition maps accordingly

 

You can do it with any of these set ups.

When you aren't in boost you are just using the lower portion of you map.

 

Thanks guys, Now for the ULT, I was guessing that a 16X16 map would become to coarsely divided to span the full Map V range? Am I wrong? Or do you use two maps - one below Map V clamp and one above (in boost)?
I'm confused . . .

 

Below boost your stock ECU handles it with no correction required from the Ult.

 

You could use "I/J Adj Map 1" and "Ignition Adj Map 1" for out of boost and then use You could use "I/J Adj Map 2" and "Ignition Adj Map 2" for when you are in boost. Would give you a 16x16 map for both in and out of boost. I currently leave everything on my car below 0 psi to the workings of the ECM and use the Maps to tune in boost.

 

Ok I think I got it, thanks. Right now my stock ECU handles the out of boost, and its all fine. I'm poking around at some other stuff whereby I would want to tweak the out of boost inj and ign just a hair - I'l give it a try.
