Oki..im a newby..and dont understand much but im looking into it..
Fact - i am poor and looking at absolute minimum budget...
For - 4age rwd
Question(s) - what is the difference between an aftermarket ecu [like ems, microtech] and an Apexi SAFC?
Is there a specific Apexi SAFC for every car? Or is it all the same just a different harness?
How much for a harness to suite for either unit?
How much power gain is expected from either of the above?
And finally..price..i see some Apexi units going for like 300 or so and the ems, microtech etc going for abit more then double...
How much would it cost for a tune for either units? Any1 want to recommend good and cheap place?
