LMAO, woops forgot it was L67(in the heading DERRR), yeah no worries post screenies of what you want added & I'll see what I can do!

[immortality]

I put a screen dump in my previous post. I think that is what is required but wiser minds may suggest otherwise.

Much appreciated.

you might need more cold fueling then, have you got a wideband hooked up?

mace throttlebodies suck for tps voltage v's throttle stop screw position and other things more hassle than good LOL

What sort of TPS voltage should you see when the TB is closed?

The TPS has a little bit of adjustment.

No, not yet.

The WB will probably go into Duece's SS for tuning first.

Might have to get another one. Might try one of those new 14.7 units.

O.K. I'm not at work to test but here is a quick mock up if anyone else can confirm, but it does look pretty close?

my mate and I never had issue with his TBs, they work great.

I made my own once too and mace supplied the TB plate to my specs, perfect fit! Funny thing is we had them years before I even known of this forum and 12P and i checked a mace Tb to see how far out the IAC was. was dead on 30 steps and never touched otherwise. TPS reading are perfect too.

I guess you must of got a dud lol


When i do the stop screw, I do it by feel and visually check if its off the engine for the slightest gap so it doesn't jam but otherwise its closed. IAC steps always around 30 when I do this.

Hey Guys,

I haven't gotten any further with this yet. Been playing with a friends 355.

I've not ever had to add in tables so I'm not 100% at exactly what I'm looking at or need to check.
