Bosch 0 261 200 162 Ecu

[Goran 3]

The story goes like this.. I've got a remaped ECU in my 205 8v and injectors from Fiat Tipo 16v

 

I went to check my AF ratio and it came up that the original ECU gives more fuel then the remaoed ECU wich was made to give more fuel in higher revs... The remap was made before i put in the injectors, and the original was pluged in only when we were mesuring the AFR .... so the only logical conclusion would be that the ECU has a long term corection. that information i cant find anywhere...so if someone knows please tell me

Dare i ask why Tipo 16v injectors ?! .. also what did make you thinking it needed remap/different injectors in the first place ? cos the OE injectors are good for well over 130hp ..

 

Is the engine modified ? cylinder head precisely ?

Cylinder head ported,polished,lowered by 0.7mm, Kentcams cam, adjustable pulley and remped

There is no long term correction. The ECU gets the injection times from a table in the EPROM and the O2 sensor makes corrections to part throttle loads. If you want to experiment a bit, put a 3 row Mi16 "167"chip in the "162" case.

so if there is no long term correction what could happen to give this results that i mentioned in my first post... anybody have an idea?

This just doesn't sound like like good job done aprroach/cycle ...

 

What did you do with the ignition map/trim ?

 

Id fit back std. injectors and std. EPROM , and redo the mixture measurement with WB sensor .. then proceed with adjusting accordingly to the test/measurement results ..

Also , ignition map is , very important ... you most certainty need different map with such modifications ..

The most funniest thing is that it was mapped and it gave more fuel and the firing angle was moved to advance in high revs... after that i fitted the injectors and the mixture was richer with the standard ECU ( way to rich, ofcourse because of the injectors) then with the maped one...

Did they do the ignition mapping on a dyno? I'd be suspect if they advanced the ignition without.

it was made without a dyno just for a test, the fuel has been added 10% in high revs and ignition timing was moved 5% to advance in higher revs ...so if the map isnt good it still should give more fuel to those 16v injectors than the orginal ... but it's the other way around

Have you checked the flow rates on them, id be tempted to ditch them and have a look at 1,9 8v injwctors
