ok, i have a long running debate with my friend regardin auto vs manual ecu's... i have read on here to use the computer that goes with your tranny and relayed this information to him but he claims that you can use an auto computer he claims his friend is running a P13 AT on a 5 speed H22 swap in an accord... so my question is... WHAT is the diffrence? i have searched and found some info... for example there are diffrent jumpers? or whatever in a P28 that you would remove to make it a manual computer... but what do they do? does an auto computer make the motor not reach its full potential? i just don't understand how they differ and i really need a solid answer to prove my theory... any help?
