Timing differences between FCs and FDs
Is there a timing difference between the FC and FD, such as a base timing difference. I ask because I am using a microtech LT-8X that as far as I know was supposed to be programmed for a FC on my FD (with FD ignition, crack, etc setup). I think i read somewhere on the forum that that there is a 5 degree difference between the crank reading between the FC and FD.
The question is do i need to make any adjustments to my microtech settings to compensate for this difference if there is actually one. So that I am not reading the timing incorrectly and making it too advanced or retarded and melt my motor? |
Anyone?

Nobody knows???

FD only has a -20 ( 20 ATDC ) mark ( trailing )
FC has a -5 and a -20 mark you have to set the L/T split to 15 degrees and use timing light on T1 and line that with the FD mark to be sure leading is -5 |
Have you ever run a FC programmed ECU on FD? Is it safe?
|
Anybody?
Does the FC and FD setup have different number of teeth on the crank that sensor pick up the rotation timing from? |
FC and FD use the same trigger settings.
|
So if i get my FD with original FD crank sensor started using a FC programmed ECU i should be fine? All is well? Just proceed like normally?
|
Yes

thanks alot

Im almost positive but even if it was setup for the x4, as long as you use a "smart" coil that receives a 5v TTL signal it'll still work.
|
its an Lt8x that used run an FC, not X4 box, but internal ignitors. Any problems there?
