Just finished installing a t3/t4 HMT kit on my friend's LS integra. Using 450's and Uberdata. We are getting a custom exhaust done so right now it is running open turbo ( We haven't driven it, only started it) I know it is running a CEL from the o2 sensor that is missing, I am wondering what effects that would have, if it isnt reading the Uberchip and is in limp mode with 450cc injectors running a really rich 240 map, would it even start. It starts, and runs crazy rich and idles like a really gnarly boat motor. So, either the o2 is making it run rich with the Uberchip working and that is the only problem or it is in limp mode with 450cc injectors and an o2 sensor failure and is running richer than Donal Trump. What do you think? How do I check what code its running?

 

You have to jumper the service connector. Then your CEL will flash on the dash the code.

O2 would throw a code unless you put your chip in Debug mode, or at least disabled O2 heater.
