I know this may have been covered before but i am not the most knowledgeable on this subject.I have a 89 lx that has a new motor that is almost equal to that of the 93 cobra similar specs, e-cam, cobra intake gt-40p heads 24#ers adj. reg. etc. the car has a c&l meter for the injectors and it has the stock ecm.Now if i was to change the stock ecm to the cobra ecm and get a 93 cobra mass air would the car be able to run better than it does now?it seems like it runs like crap until it warms up.for ex. it seems to be running rich with a stumbling idle.Almost all electronics are new tps, egr,o2's etc. would that be a worthwhile choice or should i just get a chip burned?Sorry if this seems like a repetative question.Thanks in advance.
