Sorry to hear the bads new Nick and hope they get it sorted quick and as cheap as possible for you. Not all true, it was 2 cases of beer Was good to meet you to and hope to see you and your car running at some point in the future

cheers Mate

Turns out much of the problem is down to the map being modified from a turbo one which see the boost/timing of a turbo and s/c as something completely different. Klassen is working on modding the map as he needs to find some info regarding timing which is buried somewhere in it.

I can understand that an SC needs a different timing advance than a turbo engine, but don''t understand why Klasen needs to "find" buried timing info in his mapping... Is that part of the Z20LET ecu mapping not (yet) easy to adjust???

PS; I can dig out a typical advance map (boost vs. rpm) for an SC ecotec for you.

And with all that time and money spent, you could have a Syvecs or a Motec

Here's a timing map of the Supercharged 2.0 LSJ Ecotec engine, but no idea if this remotely corresponds with your current Z20LET mapping:


(Left axis is Cylinder airmass [g/cyl])

V.poor Nick But least you will miss this crap April weather

Stand alone ECU correctly calibrated you know it's the only way

I wonder if there is a simple way to xref MAF to cylinder g/cyl , other than g/cyl = MAF / rpm / 60 / 2 bangs This is assuming the xguage figures from the MAF are g/s

I gather he has hit the limit of the amount of timing he can adjust at a particular stage of the map , If I remember Jon said he needs to find buried in the map another value to adjust as this ecu seems to go into some default safety mode, I think it is confused as to why so much advance is being asked for.

Interesting to see how it looks TA

Thank you so much and Atomx also, neither of you will get a ride now (IF when it works properly) Do you happen to know my wife she normally says things like that

I still haven't sold the DTA so I have a backup plan

[NickB787]

Going to CMS on Thursday as Jon has said it's there, I will put the 80mm pulley back on till I find a way of reducing the IAT over the long term.

Klasen found the hidden stuf then?

Klasen found the hidden stuf then?

Based on Nick and Joe's most recent posts... It looks like he has.

If so those two should be really bloody happy. I just need passenger ride now.

[techieboy]

Different things. Nick is going with the turdo ECU and Joe is going in a different non-Courtenay/Klassen dependant route. Fingers crossed for tomorrow Nick. Be nice if you can finally drive the car again before summer washes away entirely.

if anyone does want a z20 ecu wiring harness and ecu for a supercharger let me know before i set fire to it while perfroming an ancient war dance

Wait for nicks result.
It may go up in value

[The Batman]

it should do as the other tubby ecu harrop stage is emant to be running sweet..
