Post up screenshots of all your accel enrich tables and windows.

here you go

Seems your rpm bins are a bit off.

I would assume the 1000rpm still needs more then 0ms,
but the 200, 300 and 400rpm should more likely be 2000, 3000 and 4000 rpm.

[AVP]

yes indeed. i handt realised im supposed to play with those as well!!!!

i now used: 1000/2300/3800/5000 rpm

here are my idle settings

Awesome progress there.
I've been up a roof all day so not able to chip in my 2p's worth.

this setup seems to work perfect on warm engine. I must do more tests on cold engine to be sure it it adequate there as well.

as for the accel.enrichments, i did some modifications and hopefully test them tomorrow.

I must spend some time now on fine tuning my VE map up to 0.5bar (mechanical boost) as there are some differences with the motronic one,I have turned the EGO correction completelly off and pushed the VE values a bit higher up for safety,and tomorrow im going to datalog as much as i can.

It is interesting that although i have up to 45deg advance on after 4500prm and up to 102kpa, on motronic and same runs i get no more than 820C EGTs and on VEMS i get 870C(of course i dont know the lamda values of the motronic per se, but the 870C value i get with quite a rich high rpm values ( up to 0.90-0.87).

When i tried to reduce the advance, i got an increase of EGTs.... strange....(even with same lamda values)

[rob@vems.co.uk]

Lower advance always results in increased EGTs.

[AVP]

but im already using higher advance than any other map table i have seen!!!!

what else could it be?

[gunni]

Your worrying WAY to much about your EGT´s at this stage.

[AVP]

well should i use that as an indicator as well ?

[gunni]

EGT´s are nowhere as important/worrying as people tend to think especially is the engine is running fine.

Just map the fuel and ignition.
Preferably on a dyno.

[AVP]

here is my spark table.

it appears to be working on motronic,although on motronic it is derived from 3 i think separate maps, it appears that vagcom logs give me this more or less(as well as eprom reading)

so im building the fueling based on that map for starters. So far it appears to work fine.(up to 0.5bar boost though)





any suggestions/pointers?

[AVP]

also motronic has an advance/retard vs MAT feature which retards the map by 6deg when MAT is >62C and 9deg if MAT >83C

on the other hand it advances ignition by 2/3/5 deg on MATs: 28C/21C/5C

that would give me some room on the map.Still Motronic has various side maps which i dont know how they correlate with those base figures and what changes are done in them.

[gunni]

Why are you building a map based on a motronic map?
Why not just tune your ECU?
