That is very encouraging... I will try to do this as soon as i can. Does the VEMS system have a way for using the stock Throttle Body or do you have to use something else? With the MegaSquirt system most 16v owners resort to buying a BMW 325i Throttle Body, and it ends up looking like crap. I would prefer to use the stock throttle body, but apparently, it is very hard to integrate a TPS sensor into the throttle body... How did you go about this?

I am taking my injectors and cold start valve to Mercedes next week for testing (my mech is going to do it for free ) However it is supposed to rain all day today and tomorrow so I may not be able to get much done the next few days, but there isn't that much left to go back together anyway.

Thanks,
Jim

I use the OEM one.
What i do is that i take it completely apart and put the TB axle in the lathe.
Turn it flat at the end where the TPS goes,and then drill a 5mm hole in the end of it.
Take a metric 8mm bolt...and turn it down to 6mm.

Tap the TB axle M6 and likewise with the modded M8 bolt.
This way i just screw the modded bolt into the OEM TB axle and tighten it up together with a drop of loctite,and then cut to appropriate lenght needed to operate a "real" TPS.
TPS i use is a Ford EECIV/Haltech.

Itīs fairly small in dimension and will fit the OEM intake.
Use two M4 bolts to hold the TPS to the OEM TB.


Injectors.
Try them yourself.
Easy as pie.
Unbolt the allen bolts that retain the injector bosses to the intake manifold.
Lay the injectors-still connected-ontop of the intake.
Release the latches for the airfilter.

Have a helper turn on the ignition while you VERY gently(approx a mm or so)depress the KE flapper disc downwards.
If the spray pattern of the injectors are ANYTHING than a mist...itīs replace time.
It is imperative that they produce a mist even at very low depression of the metering plate.(as minimal as you can do it even)
Point is that when the injectors get crud/resin in them the first thing to show evidence of this is the spray pattern,and then mainly at low loads.
