Hey everyone,
wondering if I can get some help.
I have a 2010 GSR with AEM intake and Ultimate Racing exhaust, Downpipe, and test pipe.
What Cobb map should I use? stage 2? Or is there someone out there that has the same set up and won't mind sending me their map

I've been getting pretty lean values around 14-16 AFR. Normal for stock tune?

any help is greatly appreciated

 

A/F when cruising or idle should be between 14-15. If you have a full turbo back and intake, stage II may be your ticket for a proper tune file. OTS maps aren't the best and a dyno or e-mail tune from a reputable tuner should be used.

Thanks MattACK, the AF I normally get when cruising in 3/4th gear is around 15-16. when at WOT, I'm around 12-13. Today I did get a weird idle that keeps skipping around 1-1.5K rpm but it disappears after I drive for a bit. I'm thinking I should take off the test pipe and put the cat back on so it won't idle weird and hopefully that should make me more rich instead of lean
afraid my engine is going to blow

there aren't any good tuners in my part of town and I don't think my car will survive the trip down to the states to get a proper tune.
any suggestions?

 

any air/fuel at WOT should not be over 12. That can be very dangerous. Don't drive it hard until you can get a tune or you may have a VAC leak. Have someone that knows their stuff look over the car.

 

hey everyone thanks for all the help and input
I put in the stage 2 AEM map and did some data logging. I've been trying to compare it to values that other people have been getting and I think my numbers look normalish....I looked at the spark plugs and they don't look white so I don't think I've been running lean

Can anyone else have a quick look and give me some feedback please?
thanks so much!

Hey T-Pain, I'm looking to get the Cobb AP and an AEM intake.

What was the outcome of running the Stage 2 OTS map? Is everything smoothed out now?

 

I have the AEM intake and AMS turbo back on my 2010 GSR running Stage 2 OTS map. I have been over boosting and spike at 28 PSI. It won't stay up that high it drops down and holds at 19. Because of this I don't get in it hard. Everything smoothed out to me though. Going to the dyno to get some power numbers and AFR's. I want to see if they can tune my car to run with that 28 PSI spike because I love how it feels.

 

oops sorry forgot about this thread. OTS hasn't smoothed out and i do get spikes and a few times where it feels like the car goes into limp mode. obviously not often but it does happen. I'm still data logging and getting a pro tune tomorrow.

 

Mine spikes at 28psi then holds at 22psi

I'm making 358hp/374tq on it (according to AP). I have aem intake, ETS UICP FMIC LICP, and ultimate racing TBE with 800cc injectors. I'm running regular ACN91 coz the lwg is too rich.

And yes I use stage 2 + dw800cc map

 

@Panda_stunter,

That sounds in line with the map's spec. How's it ride? Any problems?

 

A burnt out stock clutch is the only problem. Haha! Oh, and I still have to clean my rears coz its still kinda rich afr, but it's on the sweet spot rich afr.

 

Go stage 2 baby
