Hondata

Hey all.
Just wanted to get some consulting on a issue I’m having.
For refrence, I have a k24a swap integra with a 04 auto rsx ecu with kpro4
Car has had no issues regarding ecu turning on at all. It’s been running for 3 months now, with about 100 miles on the car.
Yesterday I attempted to wire up and covert my CSS to VSS following VTEC academy’s guide. Re pinned the plug on my rsx k tuned wiring harness, then got to repinning ecu.
I de pinned the 3rd wire on the c101 plug per directions, then ran a new pin from there to B11. After making sure connections were good, I fired the car up and it ran for about 10 seconds, then died.
After that and since then, hondata reads ‘offline’ with laptop connected and fuel pump does not prime, car Dosent start either obviously. I’ve retraced all my steps and rewired everything back to what it was and still no luck. I opened the case on the ecu to see if there was any burn up/ charring and there wasn’t.
After this I realized There was one exposed wire down by the ecu but it was not touching anything during startup.

Did I just fry my whole ECU? Fuse for ecu looks fine, I just don’t know what to do or try next. Any response helps, thank you.

Try your ECU on a known working vehicle and if it still does not work then is sounds like you have damaged something.

I unfortunately do not know anybody with the same setup as mine nor do I know anyone with an rsx since I’m using a type s harness. I’ll work on trying it in another car though

Tested ecu in working car, everything turned on exactly how it was supposed too, still having same problem with my car.
Please assist

If the ECU works on another vehicle as it should, then there must be a wiring issue in your vehicle. You will need to go over any wiring that has been changed and make sure it is correct. You may need to have a shop that specialized in wiring take a look at it.
