De cat on OEM ECU

[Phil r type]

Hello , is anyone running a de cat with OEM ecu ? Been looking on the web to see the effects but can't find much . any one got over the engine light coming on ? Anyone not get the light on ? Was the fueling OK ? Any help would be fab

I ran tests on my ep3, and from what I remember the fueling was fine. I'll try to find the data.

You do need a lambda spacer in place though. (£10 eBay job)

My data log from the ep3. Average of -2.5 and -3 percent taken off the long term fuel trims. I ran it on ep3 for 10k miles with no remap, and eventually got rid for noise overload, but otherwise, no issues.

Thanks for that , was it a right angle spacer you got or just a straight spacers ?

I had 90 degree one. Either should work though
