First time swap. Car won't stay running, rough idle

Post by Marshalll »

This is a long one but ultimately I have everything hooked up I'm trying to get the car started. What I'm looking for is a either guide/fourm/checklist/answers for why the car won't start. This is my first swap.

It's a stock motor k24, cable throttle, stock injectors, headers/HR intake.

Car starts for a few seconds (2-3 seconds) then dies. When it's running it's not smooth, it's stumbling.

Car has good fuel pressure according to the fuel pressure reg. (About 40psi)

According to kmanager map is ready values and does flexuate when started. Tps sensor is also reading correctly.

Spark plugs and coilpack are brand new (both ngk)

Primary o2 sensor is hooked up. However it is showing 0 voltage on kmanager.

Multiplex is disabled so is the secondary o2 sensor

Getting a error for the iat high voltage

I'm loading the calibration for k24-tsx-stock.kal

Below I've attached a screen shot of the sensors on kmanager. This is a screen shot of it in mid idle before it dies.

Hondata just came back from HR about 3 weeks ago.

Are you using the K24 crank sensor, or a K20 sensor?
