Crank no start K20z3 RSX

[jenko301]

-what vehicle you have: 05 RSX type S
- serial number of your K-Pro: 2068-701644
- version of software being used (from Help, About) 4.5.9.0
- ECU part number : 37820-PRB-A07

Trying to figure out why the car will crank but not start, I've disabled immobilizer and a few other things. Car starts no issue on the stock ecu, as soon as I plug in the kpro it wont fire up only crank. I tried a map I had on a k20z3 eg swap that ran fine and that didnt work so I tried to load up a new k20z1 map and same thing. On the z3 map I get 2 error codes of P1259 and p0010, but on stock ecu only codes are for the o2 sensors. I believe when I tried the z1 basemap it had a tdc code as well as the p1259 and 0010.

What is the serial number that is on the K-Pro board inside the ECU?

This K-Pro was prepared for an 02-04 RSX and was not modified for use in an 05-06 and I'm guessing you do not have an adapter harness either.

No I don't have a jumper harness, Figured since the eg was working with the k20z3 so would this rsx. Guess I was wrong, that would be whats preventing it from starting?

Edit: After thinking about it more I think the eg did have the jumper harness on it, sadly got sold with it also. Thank you for the help.

The ECU must be modified and used with an adapter harness in an 05-06 RSX: https://hondata.com/products/kpro/kpro- ... uage=en-gb
