K20z1 reflash 2 Car won’t start

[Boback1]

I have the ktuner in Ecu for my 05 rsx type s. I uploaded the reflash 2 for Intake,header, exhaust , followed all the directions after the upload and the car wouldn’t start. Tried it multiple times with no luck. Reflashed my original tune and the car started up. Now I will admit I got this car used with the ktuner in it and I don’t know what tune is in it but the car runs with it. Is there an issue with the reflash 2 ? I haven’t tried another tune from the list yet.

If you're able to connect to the ECU after flashing it, you'll likely find that immobilizer is disabled in the tune that works.

ok that makes sense. So do I just need to flash the new tune and then disable the immobilizer before i start it ? or disable it and then flash it ? If so is it just a tab that i need to uncheck. Thank you.

I found the disable tab for it. I'm going to try it later today and see if it works. Quick question , Is it ok to run the intake,header,exhaust tune with a stock exhaust system ? i have the intake and race header but no exhaust yet. it comes in next week.

The tune takes advantage of the extra flow. It may be OK, but might run a little rich if the flow hasn't actually increased.

ok thank you for the help.I was able to upload the relash 3 and car runs good. like you said just rich during wot pull. but everywhere else is good. now i just need my exhaust to come in and a dyno tune.
