Wanted: 75 3.0 Motronic engine AR61503

Hi! We (me and the owner of the car, a friend of mine) are looking for an 3 litre engine for a 75 3.0 Quadrifoglio Verde, engine code AR61503. We are in Italy, near Trieste (north-eastern Italy). Also selling a 2.5 engine, AR 01646 in excellent conditions (photos arrive in a few days). Thanks in adv...

Re: Motronic M1.7 fault code "1252"

and I don't see any performance difference at normal/low speed driving (under 120 kmh)... maybe it's my imagination but I noticed a different behaviour at low rpms with lower gears [rpm fall slower under 1800 rpm with speedo signal supplied to ecu]

Re: Motronic M1.7 fault code "1252"

I'm looking for that chip to find out if there are differences between that and 022 I already own.. maybe nothin' related to speed control... signal is a square wave on 75 (0-12v), I created a frequency divider (with a 4013 d type flipflop): now 164 ecu cuts power @ 190kmh... but I'm still looking f...

Re: My Alfa 75 1.8 Rally race

Hi!
Great car!
Can I suggest you an oil cooler? A sandwitch thermostatic plate from a 2.0 8v 155 with longer tubes and a good radiator helped me a lot with my old 1.8 :) Toghether with a TS radiator (or even better a TD ;) )
Compliments!

Re: Twin Spark Engines

Hi Mats! The car will be used for road and sometime track and it will be another 75TS ;) Some pages before I read that porting on 155head is difficult due to oil "return" gallery and that you achieve better result when porting 75 head... is this true? i thought that 155/164 heads are bette...

Your fan from Italy :)

Hi, I'm an italian student of electronic engineering (in Trieste) and I own a 75 TS ASN (limited). Many compilments to you! You're great! And compliments to Jim for its book (4 cyl.)! I bought it some months ago :) Some photos of my car (shot in 2008): http://img508.imageshack.us/img508/6869/asnpost...

Re: Twin Spark Engines

Hi guys, I know this thread is quite old but you're great (I found you after buying Jim's 4-cyl book) and I have a 1991 75 T.S. with 160000km on the clock. I also have 2 engines, one from another 75TS (I have to open it because an injector oring was missing and the engine was under rain...) and anot...

Re: Motronic M1.7 fault code "1252"

Hi! I've tried an ECU from a 164 (ecu 0261200659 eprom 1267357022) which previously annoyed me with 1252 error code... now the light stays off but ECU cuts power when I reach approx. 95kmh ... maybe speedometer pulse signal from 164 has different frequency/speed ratio compared to 75... (and to 155) ...

Re: Motronic M1.7 fault code "1252"

Hi, I found a '92 2000TS8v cluster... If both (75/Milano and 155) speedometer sensors are reading speed of differential pinion, the speedometers should have different ratios between signal frequency and car speed. This because 75 TS has 10/41 diff. ratio and 155 2.08v (both run on 195/60VR14) has 17...

Re: Motronic M1.7 fault code "1252"

hi! I've got the same problem running my TS with Motronic M1.7 when I use late ECUs which incorporated this function (155s post '94 have this feature, '92 155 ECU doesn't). I'll go to the junkyard next week to remove a 155 dashboard: I'm going to study the ratio between impulses and meters/miles for...
