still to this day you get people selling chips based on rally car maps that do not have the closed loop fuelling part of the software written in
thats true,,,,, but thats just guessing,,,, theres LOADS of other things we could guess too,,, it may have a aftermarket ecu, it may be running on carbs but unless hes mentioned that ive always based my judgement on what IS MENT TO BE on the car,,, if i was to wonder " what if" with my customers i would never sell anything
so 90% chance that if that guy has a lamda sensor its got closed loop from the factory, i could have also said cat but alot of people remove cats claiming its for performance but in reality its also down to money when the cat fails
another way is to check the fueling,,, if its .9% CO then theres a good chance its got closed loop...... if its running 3 to 10% co then theres a good chance its either been taken out the chip/got a faulty lambda/ missing the cat or just dont have closed loop
hope that explains things a little better
