the Additional adjustment map is set to the stock map but has a choice for the greddy pressure sensor. should I change it and upload or just wait until I retune and have them mess with it. I have a tuning date on the 17th so I guess I can just have them look at it.

 

I don't see why the tuner would not use the pressure sensor for additional fuel adjustment. Maybe it was an oversight. Who in GA did the tuning?

I don't know if you change it now if your current fuel tuning scaling will be shot to hell or not. I'd change it on a copy of the .GSC file and see if it changes any values on the map, or effects the scaling.

 

mainstream performance did the tuning. I am going to balanced performance this time around.

 

Ed Senf at Balanced He did my car

Another good ATL guy is Scott Seigel. He was at Gwinnett Place Subaru before, but he's at battleground now.

 

Ay whats up guys, i don't have a Honda S2000 but a 98 accord coupe with the 2.3vtec. I noticed the car was in limp mode, and i was getting the same 1259 code, so i i changed the solenoid and my bank 1 O@ sensor 2. both of those would make the car go to limp mode but i replaced them both and i was driving and everything was fine...no light nothing.... then i got the code again (1259) i even disconnected my Vtec switch that i had but are you guys familiar or can u help me I HAVE EMISSIONS NEXT WEEK!!!!!????????????

 

I never actually figured out what was causing mine. I changed to an AEM EMS and haven't had any issues. I think I may have had a vtec pin sticking in the rocker portion of the valve train but haven't been able to prove it. I also dropped the oil pan and cleaned up some of the honda bond that was in there as it may have been clumping in the vtec solenoid screen and inhibiting the flow. Read through some of my old posts as they are fairly informative on the p1259 issue.
