I just finished the motor build for my b18c1 gsr swap in my 92 gsr. Full n/a build on the head with stage 2 cams, supertech valvetrain, complete fuel system with rc 440cc injectors, all machine work and everything. The car was tuned with hondata s300, and the shop set the fuel pressure to 40psi. Drove the car home, and now it is running very rich and seems to be dumping a lot of fuel. It takes a lot to start it, but after it warms up, you can drive it but when you stop it will bog down and die. It seems to be flooding itself with fuel. Any ideas??
Take it back?
If you paid a shop to tune your car, and it won’t stay running, doesn’t sound like it has an adequate map.
You can try to adjust the idle screw on the throttlebody but, YOU shouldn’t have to mess with it. You paid them to do a job, and it doesn’t sound like you got too stellar of a job done.
If you start screwing with the car and trying to work it out yourself, that gives them more of a reason not to help… How do they know that YOU didn’t cause a problem by changing and removing stuff? I’d get in touch with them ASAP.
