I am currently tuning my car using EFIsource Microsquirt. I got it running and idling very smooth. I am just looking for some guidance on ignition table. It is the base map from efi source and the only area i have changed to this point is the idle area. I have heard these cars can handle more timing with aluminum heads and i do not want to overtime it while im still using my ported e7 heads. Mods are listed below. Thanks in advance. (FYI so i dont get any backlash lol, i do plan on changing to aluminum heads and a better suited cam but would like to tune as is for now)

1988 Fox 5.0
347 stroker
+6.5cc pistons
10.1:1 compression
ported e7 heads
rpm performer 2 intake
f303 cam
Long tubes
EFI source Microsquirt
18* timing at idle

One other thing i forgot to mention is that i am running KB hypereuectic pistons, and i believe they recommend running slightly less timing?

depends on fuel used.

87- 25* at 2400rpm and slowly increase to 28* at redline
91- 26* at 2400 and 30* by redline
93- 27* at 2400 and 31 by redline

these are still safe values, you have to give the engine what it likes.

a good starting point. Not enough timing in the cruise range but again thats found during tuning.

Why the row of low timing at decel?

Actually im not sure what happened there lol. I think i meant to interpolate and might have copied it by accident. Ill get that fixed now and go from there. Thanks!
