Ok, tonite I promise to put out some decent pics as I now have the car after a 600km drive back home and a huge smile on my face!
Here's the whole story, and please be patient with me... I'm running 6psi, FPR, 1.8 injectors and turbo tony DP and free flow cat.
-The crossover tube blew 3 times on my way home... 35 degrees Celsius and hitting 6Psi not really play well together.
-the 02 clamp setting. i set it to .37 volts. Opened the black box, warmed up the engine, clamped the white wire inside the box with a digital voltimeter, and adjusted the screw to .37v. It was set to .47v. The white wire is the one i should be looking at right?
i read this post carefully, http://www.miataturbo.net/forum/show...ght=afr+vacuum
and Brain pretty much explains it. Now:
1-When I floor it say in 3rd or 4th gear at low rpms, i see a .5 sec delay, where it jumps to 15/16 afr, and then drops to 10,11,12 afrs. The AEM wideband really updates the values very fast, hard to keep up with it!
I cant honestly say i feel a hesitation. it progresses very nicely actually. But i do see a spike lean 15/16 for a split second there...
I'm will try to adjust it to .32 and where that takes me, but i'm assuming, it will always take a moment for the positive pressure to be detected and the clamp kick in right? it's not like, "light speed"? i dont have a digital camera to film the gauges, otherwise this would be a lot easier... :(
Another question is the AFRs under vacuum. cruising in the motorway, at say 130/140kmh my AEM Boost gauge reads from 16 to 0 inHg and I always see 14 to 15 AFRs. under vacuum, never goes richer than this. this is normal right? it will only go richer either in Boost or after 4000RPMs where it enters open loop correct?
thx in advance! i know this is a pain just to read...
