Maft wiring along with SAFC

[oldschool85]

I realize that it goes MAFT>SAFC>ECU but how would you wire it up this way? Which wires get tapped onto the safc's wiring harness?

Treat the Maft exactly as a stock AFM. Wire accordingly.

Was there a clear and final resolve for the MAFT and the 89+ cars (HAC sensor in the ECU)? I see that some of the folks that have it, own 89+ Supras, care to share the knowledge?

I don't think there is a easy "solution" available, since the problem isn't the MAFT, but the stock 89+ ECU, just like with any other piggy-back. The way people seem to deal with it, is to ignore it althogether, and pretend it's not an issue. The stock ECU seems smart enough to cope with it though.

so its (HAC) not being wired in then? I'm using the Lexus with venom 580cc and an HKS S-AFR, I would like to switch to this but this issue keeps me on hold.

You'll have the same issue regardless of what you use. Scaling just the AFM input, like Lex, SAFC, PHR, Maft etc. do, you'll still be relying on the ECU to learn on the fly.

Just tune a bit rich, and don't worry about it.
