Hondata

I have a P28 ecu in a 1990 crx vtec (british spec) with and odB1 dizzy and 4 wire O2 sensor installed.
The tach reads 950 rpm but the smanager s300 reads between 150-300rpm.
I CAN NOT rev above these values as the engine dies also it will only idle cold. I have replaced the iginion module the fuel pump the regulator.And the car soon as im so angry at spendin weeks of fault finding. Please help I would be so grateful.

are there any errror codes when datalogging? Post the calibration and datalog.

I am using a base map p30 B16A from the CD with out and modification with no error codes up except the knock sensor and baro as the engine is no equipt with them which i have disabled.
The inject code as i am using stock injects with the resistor box of which i have disabled.
Do you still require a datalog file?

please post the datalog and calibration.
