Af/x ecu

Can the af/x ECU manage a 2.4 swap with 12:1 CR?

more worried about the CR, want to see if it can account for the higher compression.

I would be apprehensive, if not just plain opposed to the idea. Check here and read through post 8 and 10:

I really believe that there is no advantage on the stock ECU vs 10.9 comp (on the contrary, I suspect that I get more power out of the 10.9 set-up. Just because of the way the stock ECU pulls power).

As for with the AF/X ECU (from the same thread);

I wish I still had my AFX ECU. I would love to try it on this set-up with pump and see what happens.

In theory, it should work the same way as the stock ecu (as in adjusting for knock situations etc.). BUT it shouldn't do the crazy power pull that the stock ECU does. Good, but is it too good? How does the 12.5 comp with pump gas react to the higher timing maps and leaner mixture of the AFX ECU?

I would hope that it would react like we want it to without burning a piston, but I don't really know. I'm inclined to think that it would give us a quite a bit more power (I mean the 10.9 comp engine went into the upper 160whp's with the AFX ECU and a safc, so it seems like would), but I can't really make that statement safely.

BUT keep in mind that I'm not afraid to burn up a piston for curiousity's sake. Are you?

No problem, glad it helped

Honestly, its all the guessing from chair jockeys that motivates me to waste my time and money doing this stuff We now have definitive, emperical proof to work off of. Instead of some guy with a turbo on his car saying "Compression too high! Compression too high!" like chicken little warning about the sky falling. We can show that it does indeed work and give the limitations of the set-up.

That allows other people (like yourself) to work off that same info to decide if they want to take the next step. Its all about us helping each other out, instead of tearing each other down with conjecture and arm chair theory

Ok, end rant

it wasn't really for me, it was to see if i was giving someone else good advice or not.
which... half the people here don't know how to do that. I try to keep my info based on fact and sound reasoning.

Do appreciate it though! (credit was given to you also.)
