Hello Everyone i know this question probably been beaten to death. but i cant seem to pull any code from the Blue plug with paper clip. Do i pull the code from the OBD2 plug by the driver fuse box? The car have a OBD2 to OBD1 jumper going to a P28 running Hondata s300.
Brought the car like this, The car is back firing at 4k RPM on all gears and Neutral and probably running on Limp Mode with check engine light on. Any help would be a Appreciated

Spec of car if its help any

JDM H22A
P28 chip with Hondata S300
New Plugs and Wires
just cange the Oil

 

Hondata should tell you whats going on... hook into it and see whats up

 

Did you try jumping the service connector located above the ECU?

 

Thats the thing I dont have the Plug for ECU. Previous Owner didnt Give me one, Any special USB plug i need? or Standard USB Plug?

Thanks
