I noticed that 2.920 is out. What are the changes in that version? Is there a change log somewhere that I can refer to.
Maybe unrelated but I have from time to time had a problem with WUE still being "on" in Tuner Studio when I am well past the warm up enrichment temperature defined in my MSQ file ...

Matt, can you point me in the right direction as to how to do that. Currently running 2.905 code, not had much look with the autotrigger code.

yes, I am using a 36-1 trigger wheel BTW.

so I was getting 8 squirts after all. Back to my original question, why can I not select 8 squirts with 4 cylinders and non port injection.

Thanks Matt. Looks like I had better do some more investigation then.

Matt, are you quite sure of that? When I change it to 8 cylinders and 8 squirts the change is nothing short of a miracle. No amount of tweaking of the VE table can get it to run that well, especially at idle.

I am injecting a siamesed port 4 cylinder engine using a wet manifold system. It runs very well if I use 8 squirts alternating. Since it's not port injected this would not seem to be a illogical setup as it does not matter how many cylinders there are since I don't have an injector in each port ...

My tank was not in good shape and after killing a couple of pumps I now filter before the pump and have not noticed any problems. My filter is around 18" from the tank outlet and about the same from the pump inlet. The filters are GM all metal standard injection type units.

Thse type: http://i17 ...

You are 2/3 correct. The wire goes from the ignition +12v to pin 8 on the module and to the middle pin on the EDIS coil it does not go to ground, if you connect it to ground you will short out the ignition +12v and get at best a blown fuse and at worst smoke.
It does have a 25Uf capacitor from pin 2 ...

Very usefull!

Thanks Charles,

Mine seems to be a combination of the two. It's a rotating vane type but 2 wire. Any idea what car has the VDO 408.202/008/001 . I think I will write off my $25 and go find that one if it's known to work well.

Its a bosch 0 280 140 502 as used on Saab and Volvo. One side is to 12V and the other pulsed to ground by the TIP122.

Anyone else tried this valve??

Using MS2 V3 with 2.850 beta code.

My Bosch 2 wire PWM is fully closed at a duty cyle of 6% and fully open at duty cycle of 0%. Is this normal as it seems to be a very compressed range and gives very little control of idle speed. I have tried it at 40Hz through to 80Hz and the results are quite ...

tried a Socket (www.socket.com) on mine. http://www.socketcom.com/product/connectivity/bluetooth/CS0400-479.asp

It worked most of the time but its an expensive solution compared with a short run of cable an a db9 hidden under the dash and I didnt find it reliable. Loads of dropped comms and flash ...

Mainly for European cars but may be usefull to someone as the site includes some GM part numbers.
