Luftmasse-Hitzdraht 2.2 ECU
Posted: Fri Aug 02, 2013 1:50 pm
I’ve decided to start a thread on the Jetronic ECU found on the right-hand side of the driver’s footwell (in RHD cars anyway). That’s the one that controls fuel mapping.
The Jetronic that that lives in Pollution has a serial number 0 280 000 959.

The reason for starting this thread is…………Robou has done some fantastic work on the EZ210K ECU that lives in the centre console, among other things making the boost run higher and come in earlier as this unit controls boost for the B18FT, BUT I want to read the fuel map mainly to gain experience in how to do this and also to see if any useful changes can be made. EZ210K ECU from Ray le Otter is with a red label, serial number 0 227 400 194.

I have an S70 also with Motronic 4.4 management system modified by TME but that is a little advanced for me at the moment. If I gain some skills looking at the Jetronic I will hopefully be confident enough give Motronic Suite or Turbo Tuner a go for the 70-series engine management. Anyway I like DIY stuff here goes….warning: progress may be slow I’m just learning and don’t have lots of free time anyway....
First off a little info on Jetronic:
http://en.wikipedia.org/wiki/Jetronic
Volvo 700/900 series cars had similar systems although later cars were went up to 2.4 managment. Also some of the Porsche 928's had the same so we are in good company
As stated in the link above "the most common variants are LH 2.2, which uses an Intel 8049 (MCS-48) microcontroller, and usually a 4 kB programme memory". This 4 kb memory is the bit I am interested in....an EPROM.
