It sounds interesting, but I don't know how it could be done. There isn't anything specific.

Have you tired to run without the AFM and only with IAT sensor?

Im going to try after i install the new sensor and retune the car for fuel.

May be a while before i cross that bridge though. I have a feeling that it won't work but i just thought of something that just might work. Its a little far fetched but never know till you try.

Ill explain later.

I tried a few months ago to run the engine without the AFM, just using the TPS. Actually when I installed the ITBs and opened them simultaneously the stock TB with the TPS ( using both hands, one opens the stock TB which is not installed, the other hand opening the installed ITBs) and the enginge could run. I would say that it was a very nice running, but I used the stock chip and ecu, so nothing tuned.
Just I didn't have the ostrich then, so I was just making an experiment.
I think it could run... try it! I will try it again after a month or so when I have time for that.

i installed the new wideband sensor. took it for a boot and to my suprise the "stock" bin file was showing 12s afr at wot. i copied some of the timing maps from my previous tunes. i need to smooth out some of the low and high load maps.

all in all it looked like all i needed was a new fuel pump. TRE 240 same as the walbro 255L/hr pump.

just a quick thanks to Rocco from RMP for suggesting to put the stock injectors in to solve the high fuel issue.

Hi!
Did you really need to mess with the timing?

Yup! Night and day difference!

Dont forget that the one of the things that performance chip give you is advanced timing. But with that you must run higher octane fuel. I use 91octane

Here in EU the lowest octane is 95. We have 98, or ethanol with 105.

The EU uses a different octane rating method called RON, North America uses AKI. Your 95 octane is equivalent to our 91 octane, our 94 is equivalent to your 98 and so on.

Also i wouldnt advance too much over stock unless you are dyno tuning to be sure that you are making power per increase.

That's why I don't want to increase it. I don't have an external knock sensor.

Yeah, chances are you're going to pass MBT long before you start to knock from too much spark advance.

So friday night and saturday morning i started working on another plenum design. Since i dont have a smaller k&n filter and dont want to buy another one i was a little limited to the design i really wanted. This new design will not rub on my brake booster and ill have access to my brake fluid. This design has rounded corners to help for flow.

Some insulation. I used this stuff before for pattern making and lofted surfaces for some industrial design projects.



I reused the wooden pattern for the itb side



Touch n go test fitting... Used spray adhesive to keep it toghether





Some sanding...



And the comparison...







When i start the fg work im also going to make shorter trumpets with a better lip inside the plenum. I may start the fg next weekend.
