Part # on chip is BSC57B1F. This is for 36 lb bluetops. Anyway, I installed the T+ and chip today but did not have time to hook up the timing wires and did not have my laptop with directscan to monitor anything or program some of the chip functions. I have a 3" MAF from an Olds Alero that I got from a boneyard. This was one of the possible MAFS to use that I got from a list of MAFS (I think I got it from Bob Baily's website which I no longer can find). My switch settings are: ON,ON,OFF,OFF. And the dial settings are 3,0,0,0. I found the instructions to be a little confusing so I am not sure if these are correct for my car. It's an 86 GN and I am using an extender chip (Not extreme since I am using 36 lb/hr injectors). After the car was totally warmed up it seemed to idle fairly well but not as stable as my Thrasher chip, It smelled richer to me than the Thrasher with open loop idle. While it was warming up the exhaust seemed to pop quite a bit at both steady rpms and also if I goosed the gas. This was all done with the car in park. Hard to drive around since all the body panels aren' t on yet. I guess my questions are: Do I have the right settings for my car? If I find that the car still idles too rich after looking at Dscan where should I adjust things? Should I just reprogram the chip or should I maybe adjust the MAF base in the box? It actually seemed to run OK on MAF base setting 2 which is a 3.5 MAF (mine is 3"). As you make adjustments to the MAF base setting going from setting 5 down towards setting 0-is the fuel being leaned out each step or what? Also in the instructions the MAF base chart lists settings like 5% rich,10rich, 15% rich up to 25% rich at step 5. Does that mean that we richen the fuel up by those percentages over the whole fuel curve? I guess I am wondering if I may end up with a 3 1/2" setting using only a 3" MAF and if that would be normal or acceptable? Sorry for all the questions but I am obviously a bit confused. as to the best wat to set this up. Now just to throw in a glitch, I may have an injector bleeding down because the car has been somewhat hard to start recently and my FP doesn't hold as long as it used to. When it starts it seems to skip on one cylinder until it clears out after 10 seconds or so and it smells rich during this time. Anyway to tell wether it is leakink at the injector or at the pump? Pretty sure its an injector and I may attempt to run it on a can of injector cleaner soon. Once it clears up it seemed fine.
