Bmw 3.0Si D-Jet Bj 1974 - fine tunning

More photos...

The intake independant tubes

The blue dot MAP (for the blue dot ECU that I don't have... Yet...)

The NEW idle speed... First time it idles correctly since 1986...

I first tunned the CO with my nose and ear. Then, my little gunsons CO machine warmed up and told me it was on 2.2%.

I really didn't have all the information about the D-Jet. You were great!
Now I have all the D-jet parts checked.

Hi Antonio,

I have seen a few European BMW MAP sensors and I have two BMW ECUs here, one even new (old stock). They do not have colour markings. You must check the Bosch numbers on them. On MAP sensor it is punched into it and must read 0 280 100 030. for European cars or 0 280 100 047 for US cars. ECU should be 0 280 001 007 for Europe or 0 280 001 013 for USA.

Congratulations to you...

Must go to bed now.

Hope to hear from you again.

Regards
Norbert

- Did you read my posting with the user manual? I think, it's really helpful, contains much more information I'm used to OEMs give to their customers.

And after a test drive... Another fine tunning issue appears...

When releasing the throtle suddenly, the engine almost stalls (sometimes it stalls) and then makes a "saw" accelaration to 1200rpm and stabilizes again on 900rpm.
On the carburetted models of this Car, a throtle damper exists to prevent this.
And on the d-jet??

Thanks once again!

My car has a 'dash-pot', too.
But it's an Opel...

Regards
Norbert
