Thanks for quick reply. Think I have found them. Will test and let you know how I get on. How much did you manage to inject?

at high rpm little bit under 60mg.

That great. Would I be correct thinking one of the single values is @ f20aa? Again thanks for your replies, they are much appreciated

Vp44 shitty pump? :_) Same as mine..with iq limit

by **ecuedit** » Fri Jul 25, 2014 12:24 pm

iq limiters are in ecu,
and are single values. Have personally did it for exactly the sam car and ecu.
Injecting 60mg, single values limiter were set up at 50mg.

Think I have found one of them in each codeblock, im assuming there are two in each block but cant find the others.

Pump don't have limiters, Ecuedit is right. You can't inject more iq because you don't want to search and think. Everybody don't do it, but Ecuedit take his time and found all limiters in bin. SO OPEN YOURS EYES AND SEARCH BETTER GUYS )
And tuning results in this car can be filing after 20km or 3 days!!! because pump need time to take adaptations from ecu.

Not asking for the location of the limiters as I want to find them myself. Think I have found eight of them. Just wondering how many there are in each codeblock?

You are wrong guys, all limiters are increased(no one missed), personal i made logs, the actual fuel quantity is 67 mg now starting from 52 mg. With 67 mg on bmw 320d hp 136 hp original now 165 hp ..increased fuel iq to 75 and also turbo pressure to keep AFR= same power.
VP44 has internal ECM which has software to limit fuel. Read VP44 bosch manual and you will see that software from normal cars is different than Dodge cumminis where is the same pump and maximum limit is 125 mm3/stroke.
Make logs and see actual fuel quantity injected, if is bigger and bigger, then for sure that you increased the correct limiters.

Pump limitation is actually not at 50mg in this car, that is ECU limitation.

BMW does not have same pump, your car has 4 cylinders and 136hp, Audi a4 2.5 TDI has 6 cylinders and 180hp...
Pump is not same.

(if you read my all previous comments I do not mention that vp44 pump limitation is not present),
I say that 50mg is ECU limitation here, pump limitation in this car is way higher.
