See the attached file for translated ZUESZ. Here is the snippet describing calculation of dwell time.
Calculation of angle output
The basic closing time for a selected voltage (eg 12 volts) is available in KFTSRL = f (nmot, rl). The characteristic of the voltage increases FSWTM offer in the cold start and warm-up. With dynamic load (B_swdy = 1), the closing time is multiplied by the factor ftsdrl until the time of TZSUDYN has expired. As long B_swdy is active, which has been triggered by B_swdy maximum occurred tsdrlmx the source for the factor of FTSDRLW. B_swdy is reset as long as drlsolf_w> DTSDRL is (re-triggering). Calculated by then closing time is limited by TSMx upwards.
The correction of the influence of Ubatt is by the factor in the characteristic field KFSZDUB. A voltage offset between the measured and the voltage at Ubatt ignition module can be taken into account with DUBZS.
A positive speed gradient is corrected in the map KFTSDYN. The minimum open time limit applies separately to each ignition output.
I have only changed KFTSRL, FSWTM, KFSZDUB, and FTSDRLW and my tsrldyn values were indeed lower. I have not touched KFSZT.
Thanks catbed, that explains to me something: in MED9 the output variable from ZUESZ is called szout_w, but in ME7 same variable is called szrl_w, even though ME7 has another variable szout_w that is basically FSZTM x KFSZT. Now for the MED9 to ME7 transfer I did this: --------------------------------- TZSUDYN = 0s KFTSRL = KFTSRL FSWTM = FSZTM TSMXNL = TSMXNL NMNZUESA = NMNZUESA NMXZUESA = NMXZUESA TSMX = TSMX KFSZDUB = KFSZDUB DUBZS = 0 KFTSDYN = 1s--------------------------------- szrl_w (ME7) == szout_w (MED9) Also I found out that in MED9 SA(T) subfunction of ZUESZ is disabled by set very high rpm lower limit. Only things that left different were ftsdrl and KFTSDYN. KFTSDYN I have set to 1s to disable it. To disable ftsdrl correction I have set TZSUDYN = 0s. One more thing to consider: DUBZS. I believe this offset should be set to 0 if it isn't already. P.S> Some of the maps listed have already same values in ME7 and MED9, but to be non ecu dependable this list had to be such.

Glad I could help. Good idea about DUBSZ, I missed that. Another way to deal with ftsdrl correction is to change FTSDRLW to 1, since that is ftsdrl's source.

Any longer term feedback, or feedback from newer people who have made these adjustments with their 2.0 coilpacks? New people, did it make a tangible difference with these settings? Older people, still no blown 2.0 coils?

Been using the 2.0T coils this whole winter season, on E85, ~6-7 months, no issues at all, changed to the 2.0T values in january, and it runs quite a bit smoother then it did when just plugging the new coils in. noticed gain in low/mid rpm, as in; you dont have to press the throttle as far to keep the speed up. what supposedly was compressor surge is now gone, so id say the coils themself are a big improvement, esp with plugs that are gapped wider.. running ~1.1mm now, very good spark compared to the original setup.

Haven't blown a coil since I made these changes, but I also re-worked the harness so I can't say dwell time fixed it. Changed the dwell time on my buddy's stage 3, it seems to run smoother when boost comes on.

As I understand FSZTM*KFSZT is one source, but this is not used in 2.7TT (CW_FUBND=0).
I disagree, FFLDZ and KFFFANZ are the ones skipped in 551M due to CW_FUBND=0 DISCLAIMER: there could be some errors in this code but not concerning CW_FUBND From what I can tell FSZTM & KFSZT are active.

Looked into it a little, I think it should be that one logic is used only for starting the engine and the other one is used the rest of the time. During driving the load based one is always used.

Hi SnOOk , Have you done this on the 1.8T engine ?

Maybe someone could screenshot maps from fsi golf mkv? red coils code: 06E 905 115Or attach defined ols/xdf file TIA Hi MasterJ , Did you manage to get hold of the values associated to these coils ? I have these coils as well and was wondering if you could help out . I tried the search function with no luck. Am I correct to assume that these Red Tops will have different values for KFTSRL , FSWTM , KFSZDUB and FTSDRLW when compared to the earlier grey coils ? Thank you

Hi SnOOk ,
How did this work out for you ? Was it worth changing the maps ?
I have the red top coils .
Thanks

Has someone come across follow up sparks (post spark /multiple spark) in a cycle?

There was a thread that discussed multispark when dealing with e85 I believe
