I also posted this in the 92+ civic area but I thought others that dont visit that area might see it here and have an idea.
Thanks

Ok as you can see at 5000 to 5500 rpm I am losing alot of HP with that dip. here are my car specs.

D16Y8 @ 9psi boost
f-max (turbonetics kit) using the MF2 fuel controller with the two extra fuel injectors.
JE / SRP forged pistons 9.0:1 compression ratio
Crower Econo Billet Rods
Crower stage 2 camshaft with valve springs and titanium retainers
Greedy Profec B-Spec boost controller

when I am driving and this occurs at 5000 - 5500 rpm it feels like all boost is gone and the car stops pulling hard. But if I take my foot off the gas then go WOT the problem goes away and starts to pull hard again.


another problem I noticed as of yesterday is that the car is detnating coming off the line in first gear only???

I pulled the plugs and they are black which I believe indicates that the car is running way to ritch. Do you think that when I'm taking off from the line it is dumping to much fuel causing the detnation.

I believe the problem at 5000 -5500 rpm is also a ritch / lean problem.

here is a website that talks about the MF2 controllerhttp://www.aquamist.co.uk/cp/mf2/techmf2/mf2tec.html

with this controller I can ajust the amount of fuel at 1000, 2000, 3000 RPM and so on...

any help is appreciated thanks.

 

I am glad to say that I have solved all the problems at this time.

here is what I did.

The filter had come out of the missing link put a new one in solved the detnation problem.

Bought new NGK plugs.

adjusted the the MF2 controller to be leaner through 5000 - 7000 rpm and that solved the down curve it was boosting and pulling right through all rpm range.

I thought I might be getting to much back pressure in the in the catalitic converter so I made a straight pipe and took out the cat. all pipe is now 2 1/2".

It pulled very hard so I have a big smile again.

Now I just wonder what the true HP is with the drop at 5000rpm gone??? any one got a guess.
