Like it's on the verge of being jerky.....a very small throttle input yeilds too much response is the best I can describe it......

thats what I thought too....it's not too bad or anything...actually the car
is running awesome....best it's ever ran I think....
any suggestions on where to richen it to smooth it out?
That is, lo load scale probably, 1200-2000...? Mid load ? Or would it be better
to adjust it in the MAF scale portion....?

Hey, had to bring this one back to ask if some one knows if this is compatible with a na motor. This sounds like the one i need been reading a lot about it.
Can this be used on a NA sl.
Thanks

[TurboBob]

yes, it is compatible with the NA system.

Great thank you, maybe you could answer one more question for me. I plan on using this controller and its afr tracking system with innovate LC-1 Controller w/gauge. My question is since ill be replacing the stock narrow band o2 with this one how do i hook it up to my ecu like the other one was? Do i use both sensors or do i get a converter of some sort.
Thanks

On a NA I think you can install the LC1 sensor in place of the stock sensor. feed analog output 1 to the ECU O2 sensor input, and feed analog 2 to the Gen2

That said, the stock ecu may be finicky about the O2 sensor, and you may be better off having an extra bung installed, so you can leave your stock O2 sensor alone

Thanks,
I will just weld in another bung. I was thinking of putting it in the test pipe right after the stock one in the long tube header(fed spec). Dont want to put another hole in the headers, and ill be able to easily do this with the t pipe off.
Sweet.

Anyone have any good mounting solutions or pics for this tuner and where it was installed?

Ok, I'm very very new to tuning, and still fairly new to the 3S platform. I recently installed 16T turbos and 450 injectors.. I went with the GenII as I was told it was far superior to the regular translator, and that the regular translator had a tendency to drift, and would need to be constantly retuned.. Got all the wires installed, and I think the GM MAF I have is no good, it was a used one I got off ebay that was supposed to be good... but whatever.. car had a hard time starting and almost impossible time staying running, especially if I touched the gas pedal, it died.. So I went back to the stock MAS and configured the GenII for the stock mas.. The only thing I could really get out of some stuff I read last night was to set the main scale to a negative number to accomodate the larger injectors... While driving I got it to around -15% and it seemed to lean out quite a bit and was giving around 14 or so on the WB.. Other than that, I'm really at a loss with the rest of the features. My main concern with getting the translator was to obviously bring my AF ratio back to normal, and also raise my fuel cut limit. I know I'm probably asking alot.. but... Any idea what kind of settings I should start with?? It seemed to be running pretty well at -15% on the main scale and when I touched the afterstart (as I thought I would need to adjust this as I was running a little lean at idle with my mainscale -15 to -17%) so I jumped that up to 0.2 and it seemed to lean out fairly well, but threw a CEL. Like I said, I have almost no idea where to go here, I flipped through all the features last night with a giant ??? above my head... thanks.. and feel free to smack me around a bit!

All I can say is read thru the 1st few pages of this thread, because I asked Bob a lot of questions, and he is the expert here. His recommendations have been right on....
Otherwise, I think with 450's your correction should be in the -20 to -25 range...(my experience)....also, I would have larger than 450cc for 16T's but your call.....like I said read this entire thread, and make sure you go thru each screen / parameter and set it up correctly top to bottom - my car runs great (Gen 2, GM MAF in blow thru, 560 Evo injectors, twin intakes, etc...)
