Title: me7.3.1 - ignition tuning on WOT when lambda < 1 Post by: Bastek333 on October 18, 2016, 10:51:45 AM Hi guys,
Been playing with Alfa Romeo 147 2.0 Selespeed ECU about 7 yeras ago - now I just bought another Alfa 147 Selespeed - so time to play again ;D. Funny thing that my new car has the same ECU: 261206708 277356576 3501819 But I need to go back to my old tuned files and understand it better. So going back to question. KFZW and KFZW2 maps are for ignition base but only when lambda=1 - so which map is for ignition on WOT where the lambda is < 1 ?? Read http://s4wiki.com/wiki/Tuning#Timing and translated funktionsrahmen and can not get which one or what the formula is for lambda <1 Have full DAMOS for similar alfa but 444 version - and non linear offset is a pain >:( - maybe someone has the proper DAMOS ?

ZWGRU 23.110 Application Notes The maps KFZW and KFZW2 are applied when the engine is warm for the respective camshaft control position, exhaust gas recirculation is inactive and lambda = 1. If the engine does not knock, the optimal ignition angle is input. For engine knock, the knock limit is input. read from funktionsrahmen ... Title: Re: me7.3.1 - ignition tuning on WOT when lambda < 1 Post by: vwaudiguy on October 18, 2016, 01:45:15 PM read from funktionsrahmen ... looooool Actually, at first, I read this as you telling prj to "read the FR" which I found funny. Re-reading it again today, I see you meant "you read this from the FR". Apologies.

Title: Re: me7.3.1 - ignition tuning on WOT when lambda < 1 Post by: adam- on October 18, 2016, 11:45:01 PM I think he means KFZWOP.
Title: Re: me7.3.1 - ignition tuning on WOT when lambda < 1 Post by: Bastek333 on October 18, 2016, 11:50:53 PM I think he means KFZWOP. Ok so it make sense - KFZW and KFZW2 always used in short words when lambda=1 - when lambda<1 then KFZWOP with all others corrections (like knock etc.) to it as an optimal ignition map. So should be KFZWOP tuned or try to work with all others corrections maps to it (hard-way as is so many dependencies)? Title: Re: me7.3.1 - ignition tuning on WOT when lambda < 1 Post by: nyet on October 19, 2016, 12:23:19 AM So should be KFZWOP tuned No. You should do some more research. KFZWOP is reference timing for torque calculation.

KFZWOP is reference timing for torque calculation. Ok - thank you - so hard way of changes in trimming maps.

Applied means CALIBRATED at lambda 1. The maps values are filled with lambda = 1, that's what the APPL part talks about. Not WHEN they are used. There is an additional map for correction of the ignition angle through lambda shift. Before copy pasting stuff actually read what you copy paste...

Now I have the proper documentation - ME-7.3.1H-Alfa-2_0L-FunctionAndDataSheet.pdf so slowly going via over 1000 pages ;D Title: Re: me7.3.1 - ignition tuning on WOT when lambda < 1 Post by: vwaudiguy on October 23, 2016, 12:19:37 PM There is an additional map for correction of the ignition angle through lambda shift.

Title: Re: me7.3.1 - ignition tuning on WOT when lambda < 1 Post by: vwaudiguy on December 16, 2016, 10:34:14 AM DZWOLA - Lambda-Abhängigkeit des optimalen Zündwinkels bezogen auf Lambda 1 Thank you. Title: Re: me7.3.1 - ignition tuning on WOT when lambda < 1 Post by: prj on December 20, 2016, 07:22:49 AM DZWOLA - Lambda-Abhängigkeit des optimalen Zündwinkels bezogen auf Lambda 1 That is not it at all. It does not affect timing, only zwop. KFDZWKG is the one that actually does stuff. Title: Re: me7.3.1 - ignition tuning on WOT when lambda < 1 Post by: nubcake on December 20, 2016, 10:32:37 AM That is not it at all. It does not affect timing, only zwop. KFDZWKG is the one that actually does stuff. Take a look at the code, you will be surprised. Title: Re: me7.3.1 - ignition tuning on WOT when lambda < 1 Post by: woj on December 20, 2016, 02:20:51 PM Interestingly enough, on one particular instance of ME7 for Fiats, the two maps KFDZWKG and DZWOLA effectively cancel each one out.
Title: Re: me7.3.1 - ignition tuning on WOT when lambda < 1 Post by: prj on December 25, 2016, 10:18:52 PM Need to look into it then I guess, I always used KFDZWKG, as that is what factory uses.
