Hey,

I've just installed a jdm dohc f22b into my 94 accord lx.

When I start the car it runs ROUGH, I look at the plugs and it is running VERY rich.

When I check the codes, it shows a TPS code. When I put the Accord ecu back on, it shows a MAP sensor code.

I've changed the injectors, and still the same problem.

I am using the Accord tb with the built in MAP sensor.

Please help, I've had this thing sitting here for months.

Thanks.

 

Which ECU are you using? The Accord one won't work.

 

I am using an H23a and the stock ecu

 

The h23 needs more fuel because it has higher compression than the f22b. This is why the p14 is making you run rich. You could chip a p06, or buy a p39.

 

h23 also has a knock sensor, your f22b doesnt. its prolly throwing a code for that.
