So I purchased the car ~2yrs ago w/ a Drag kit. Since, I have been doing my own turbo kit in pursuit of more power. Recently, when driving the car, it will throw a code for MAP and AF goes to crap and car cuts off. I replaced the plug on the 3bar not too long ago as all the surrounds for the "pins" inside were missing causing bad connection resulting s300 to see full 3bar @ idle. Since then, I have been having the CEL problems. Note, car is untuned. Just driving around block after minor changes to check for leaks and make sure everything else is working properly.

I did wiring according to Hondata website so I am almost positiv its correct. Would this be a sign of a bad GM 3bar or could it be something else?

FYI: OBD1 car (DB8).

TIA guys!

 

Do you have basemap on it atleast? Your s300 needs to know it has a 3bar hooked up or it will throw a code.

 

Yes, I have all of that. Sorry I failed to mention.

What are the correct settings for a GM 3bar in s300?

 

I am specifically asking for is either: Custom, Motec 3bar, or Neetronics 3bar along with the scalar and offset.

If memory recalls correctly, I have it currently set on the "stock" Motec or Neetronics. Hard to recall since I havent had the s300 on a lap top in a while.

 

With a GM 3bar you use the motec 3bar in s300.

 

Gotcha. Thanks bud.

Any input on having a bad MAP or if it could be something else?

 

Problem solved. Loose tranny ground was the culprit.
