Thread: Tuning for Blow Thru MAF

Stock DE ECU, with a piggy back and retarded base idle timing would work. But we are talking about 7 psi max and base timing at like 0*TDC

I knew i should have said "stock de ecu w\ no piggyback" haha and the speed cut is at 112 mph....it mocks me regularly =(

Unless the piggy back lets you control timing, it's fairly pointless in my opinion. Your better off with a Calum Basic and some random tune off the web

Vadim we would run NA ECU's with a SAFC and 15-20 psi all day LOL ... Wow we have come a long way.

Wow that's pushing it. What would you guys run your base timing at? Stock timing map is pretty aggressive for anything above 5psi, the stock DE map I'm looking at is running 25* of timing up top.

Now if you can control timing then it's a different story, otherwise your just playing with the distributor

You always can run up to 20deg up top with 8.5:1 so thats a 10 deg base timing so thats easy jajajaja.... I have set up 850cc injectors and a Z32 maf on stock ECU with a SAFC

I used the emanage on almost every car I did a swap on and it worked perfect. I still have one on my car but not for long.

Vadim this was way back when over 10 years ago. Hell we had a T28 NX on stock cams that made 301 whp at 15 psi on a NA ECU with a SAFC and it ran for years and to top it off it was a true 10:1 UK motor LOL.

Would I do it now? Nope we have all the options in the world now. We did what we had to do with what we had.

does anyone one now how running a blow through maf setup is effected with a jwt ecu? my bov is also atmosphere if it makes any diff

So I swapped my n60 to blow through, and I'm having a few issues, the first ones rather new to me, super lean idle, I adjusted the min pulse width (AKA TTP MIN) just in the area that's bein used, an was able to get it to idle at 14.7. However if I bumper the throttle, or say I'm coming to a stop it'll idle at 18-20afr for 10-20 seconds before coming back down to 14.7-15.0, do I just need to further play with the min pulse width (TTP MIN)?

Or could this be due to my maf adapter leaking? it seemed to be holdin boost just fine, it seems louder now but with a shorter, straight intake I was expecting that.

Ok secondly, the cruise/accel/wot is a good bit richer, now from some research I've gathered I may need to lean out the injector multiplier (k value), but with my idle already bein so lean I figured I would take care of that first.

Ideas? Suggestions?

OH one more thing I noticed is it seems to spool faster, not sure if that's from the super rich afr's doin the anti lag effect thing or just because the intakes less restrictive an the cold side pipes have less bends.
