M20 323i Hartge ECU, Information needed

[jakke]

Hi all, bought myself a Hartge 0 280 001 308 ECU for future 2553cc Jetronic build.
I was wondering if anyone has any information what could have been done to these units.

Browsing through the old hartge catalogs I was able to find the same bosch number with rev limiter increased(?) to 6900rpm. https://www.e30.de/fotostory/f00604/09.jpg

I drilled open the case to see condition of the board and components, link below for pictures.

Is it a Hartge e30 or e21 323i Hartge ecu? Hartge e21 H3 was around 180hp with Hartge motor and exhaust. The e30 Hartge H23 was 170hp.

I think "308" should be a later e30 323i ecu.
Referencing number 000125 through the hartge catalogs has not been successful.

Also earlier H26 seems to be based around 323i with 190hp, but I doubt the ecu in these jetronic systems are that different.

I guess I'll find out when I get around building my engine and comparing two 308 ecus I have now.

I use to have a L Jetronic 1984 e30Hartge H26 193hp. It was a base model 323i. My friend Frank owns it know. The later H26 were 189hp montronic. Are you building a Hartge car or just the motor?

Just a replica motor, b23 crankshaft in b25 block.
