I doubt it's a big issue tbh.

The narrow band only has 0-1V of definition, therefore it is likely to be a fair bit less accurate than your wideband reading, so the difference is probably just that. As long as your wideband has been calibrated and you've perhaps used another wideband to confirm the others readings are accurate it shouldn't be a problem.

 

After trying V10.. i'd say stick with V9 firmware.

 

Been a while, heres my new map. Not many changes from last one but few on there.

 

Non select ecus... I'd recommend doing this too (when doing the other cable swaps).

Have you got a link to the original post on the adaptronic forum please?

edit:- no worries I found it.

 

Had a look at your map and mine looks like ---- compared to yours. How much of the cells on your map is tuned and how much is just interpolated and smoothed? Both fuel and ign.

Are you using slow converge and autotuning in boost?

You mention transition smoothness linked to predicted map table. Any tips on how to tune this table?

 

I started off with a new fuel map (post 1 u can see its interpolated from corners). That was a fresh map from scratch and thats the only time i've used interpolate from corners. I ended up giving up on the map Travis did and started one from scratch where the base settings were correct from the start.

I started tuning first with rapid tuning 100 rpm and 5kpa tolerance, then set the map to untune and go 50rpm then with slow coverage to 25 rpm 2kpa. I only use autotune up to 110kpa and 5krpm. My ignition... i smoothed it a tiny bit so theres no odd peaks.

In boost I log, then add and subtract fuel where it's needed then play with the ignition after that.

As of the other day i've switched to a twice more detailed map.

 

Predicted map table tunning.

This can be done with 1 person but it's dangerous. Use the F2 gauges.

Anyhow go to 1k rpm, (in gear most likely) open the throttle to 2% and see what kPa you're at, enter that on the 2nd one down,

Then again 1k rpm open the throttle 5%, see what kpa you're at and that goes on the next one under it.

then 15%, then 50%, then 100%. For 15% i got 92kpa, for 50 and 100% it's 100kpa


For 2k rpm, get the engine to 2k rpm and then again 2% 5%.... you get the idea.

When you get to the upper cells 4-5k rpm 15%+ for sure you'll be in boost. Take what kpa you got and subtract half the boost. When you first step on the gas there is turbo lag which will not be calculated if you were to do the same thing you did before. For boost it's more by feel and a good guess but it's very close to half of your max boost... then adjust from there.

So say u got 150kpa, you subtract half your boost so you'd enter 125kpa and see how that works.
