Anyone know what the offset is (in milliseconds) for #83 lb/hr Siemens injectors? Thanks,

3.5" or 4.5" back spacing on the rear 15x8's

If your VE table is close, turn off the WB correction and see if it still does it. If it stops doing this, then try to find where you have an exhaust and/or intake leak.

Can you ball park me the price on these? (PM me if you don't want to post actual prices) I already have the GM IAC motor with my FAST system, so the main thing I would need would be the IAC adapter and Ford TPS w/ GM connector.

I am contemplating changing from a 4 barrel throttle body to the more common large single throttle bodies in order to reduce air flow losses. My concern is what I would have to do to my FAST system in order for everything to still work. The main thing which I am not sure of is the TPS and the...

Norbs, Sorry, not going to be around, but please let me know if this works. I have always wondered if it would work as this might be some good tuning tool to help others.

No, I didn't say the tune looked OK, just that you need to keep adjusting the VE table until you get the Actual A/F #'s to more closely match the Target A/F #'s. Right now you are going pig rich when you step on it. Also, the A/F table seems a little course for your driving area. If this...

Yes ... I finally got a chance to look at them today. Sorry, work has had me out of the office for the past few days :mad: A few quick things ..... Your O2 numbers are off some at the lower engine / load points so you might want to start tuning your VE table. Don't know if you...

You can send me your log file too. Things I would log are: RPM, TPS %, MAP, VE, Target A/F, Actual A/F, (or O2 Correction%), and Timing. If you are having drivability issues, then you may want to log some other parameters.

TurboZ Just found this from the man (Craig Smith) after doing a search on inductive delay. I hope this helps ... (though I am concerned just how sensitive this really is :mad: ) http://www.turbobuick.com/forums/showthread.php?s=&threadid=46099&highlight=inductive+delay quote...

What if the pointer of the distributor is not quite lined up with the pin in the distributor cap? At higher RPM's and more advance, the desired timing would line up closer between the cap and rotor than at slower speeds ??????? Not sure on the logic and how it applies to his EXACT problem but...

It sounds like all you need is the DiagA number and the calibration disk to go with it ..... If we could build up a data base of these items, then you will NOT need to buy the FAST WB and just go buy one where ever you could find it. I haven't got my car started yet but hope to in the next...

I don't know if FAST told you or not, but is the DiagA reading equivalent to the resistance in the WB? The other O2 thread is currently discussing how to / if you can modify the WB resistance to work with the FAST without having to buy the cal disk.

If someone has a pin out, it shouldn't be that hard to try ... I have two friends who also have FAST systems and I would be willing to try and make theirs work with my system just to see. As norbs said, for $300, I think I could waste a weekend trying to figure this one out.

From FAST site: Points Unless specifically noted otherwise, this wire is to be connected only if an inductive pickup ignition system is used. Connect this wire to the points input wire on your aftermarket ignition system. Do not connect this wire if you are using your factory ignition...
