Hi Chaps! Great weekend wunnit!

John, I've found the site about tuning up an Alfa fuel injection system :

http://www.hiperformancestore.com/L-jetronic.htm

Although it's written for the old style Alfa GTV, and is for the Jetronic (when you have MoTronic) - it's a very good article, and most of the stuff in it applies to you guys. There is a good description and pictures of clicking the air flow meter which is what you're after.

Note, you do not have an extra air solenoid, or idle pipe, as these are controlled by one pipe into the front of the inlet manifold and an electrical connector into the vessel by the ECU.

Cheerz,

Bob

Oh, and we have hydraulic valves, which cannot be adjusted.

Good luck!

Yeah, good to meet you all in person and see your characterful cars. Amazing how different each 33 is. Hope you all had a good time, though we weren't impressed with the organisation and comments have been made. Maybe see you at National Alfa Day, which will be better, though Spa Italia, Le Mans and Nurburgring 24 hr are all on the same weekend which is a bit stupid. (I mentioned this in the last owners club magazine, but it was edited out.)

Yes, I will write about this in the next registrar article. Yeah, hopefully Ed will have his car at the Donington track day this year if he doesn't crash it at Nurburgring first. Good flux capacitor by the way.

I tried it at a 33 1,7 8v jetronic. 5 clicks clockwise 1st but finally ended 4 clicks anti clockwise than the original position. the spring at my car at least softens by turning it anti clockwise... tried it?

Ken McCarthy · Posted: Sun Apr 30, 2006 4:36 am Post subject: Air Flow Meter Mod

Tried this - 5 teeth (clicks) anti-clockwise. There is a noticeable improvement in low and mid-range torque. The car is easier to get away from stand-still without bogging down. Don't know what it does to power or to performance at high revs yet but we shall see. Increasing fuel may actually decrease power but it is definately nicer to drive around town. Don't know what it does to fuel economy or emissions either.

A word of warning. The "w" spring needed to be levered up after its retaining bolt was loosened. I had marked the gear wheel before I released it. If you don't mark it, the wheel can slip as it is under spring tension like a watch spring and you will lose the position. There is no other way to find the original position if you have not marked it.

Regards

actually at my car the noticable change was at hi revs actually had bigger top speed...As far as concernes fuel consumption it was the same or no noticable change.of course i marked the original position...As i readed the more loose the spring is the more rich fuel u have....and if u try u have loose spring by turning it anti-clockwise...

bobbber · Posted: Wed May 03, 2006 11:17 am Post subject:

How is the 'W' spring accessed in the Jetronic scenario?

Do you need to take the ECU off with the four top screws? Does this reveal the 'W'? Are there any wires between the airflow meter and the ECU or are they in the loom (i.e. from the comb connector connection).

Thanks!

Bob

Take off the 4 screws,pull the upper part, and there is a plastic cap sucked with silicone.take it of and there is the W spring
