Hi there I was wondering if anyone here could chime in on their experience with their boosted S2K on GEMU? I've read just about every thread I could find on the subject but most responses are from someone that new a guy that knew a guy... I'd like to hear from someone that's currently on GEMU and boosted. What problems does it give you? Much appreciated.

 

I ran with one at nearly 20psi and a NV1200 with ID1000. It ran like a stock NA car, id say better then the typical AEM/EMS tunes floating around, mainly because the factory ecu/closed loop is still functioning and most tuners wont take the time needed to work on this area of the tune enough. So as long as you have someone experienced with he Ultimate do the set up and proper tune, it will support a set up at a pretty high level. There is a cap on the amount of timing degrees it can retard which I started flirting with, which is 20. So taking the factory ecu timing advance of 32-35 degrees at peak WOT ive data logged and doing -20 = 12-15 degrees total timing advance, which will support most 500whp set ups out there on pump gas. So id say that's where the cap/limit is on this device.

 

Did you have to keep resetting your ecu so it would work with the gemu?

 

No not at all. It doesnt try and override or re learn anything, once you program the tune, its there.

 

I like Junky had good experience with mine, your talking about altering partial throttle breakpoints dont touch them and you'll be fine.
