i like the big VE table would be good with a 1bar having all them cells .its mapped 0-100kpa still so need to work out what voltage each cell represents to work out for 2 bar stock size spark table still also noticed a lot of tables are out a few addresses i didnt look to see if it goes over 100% VE like the 2bar$5D does or not.definatly worth further developement thats for sure a spark table to match the size and cells of the VE table would just be mega.

just to put me on the right track, I should see what sort of change in the VE & ADV tables of the new bin when compared to the ASBY. to my untrained eye there does not appear to be a significant if any difference.

You shouldn't really see any change except for the increased resolution on the VE tables MAP axis.

I think Delcowizard might be correct when he said some of the tables are a few bytes out.
I now remember not completely finishing off the XDF but I'll look into that tomorrow , a minor problem.
It should be fine for VE table mods the way it is.

:!: If you've already downloaded the ZIP you might like to do it again as I've done a change to it since I posted it. :!:

sorry Adrian, after I posted it occurred to me that confusion might rain. I was referring to delcowizzid's changes to the ASBY bin, not your 2 bar bin. looks like I need to pull my finger out and fit the sc14.

you will see most of the timing changes in the lower rpm 90 and 100kpa area and the same with VE to go with the extra timing it doesnt need much to make a good difference. top end 28 degrees +2 degrees every 1000rpm is enough really wont gain much more from going higher than that .all the gains to be had are in the lower rpm area and obviously i dont give out fully maxed out tunes due to them ending up on ebay and some of us just like to keep things a little secret for the edge on the competition :mrgreen: it will give you the idea though im sure

thanks delcowizzid, just needed a hint for what to look for. trying to get a feel for what magnitude of change is required to affect the performance. can appreciate significant changes needed for boosted or highly modified engine. hope to get the chance to give your ASBY a run today.

sweet its allready modded by hsv so it doesnt need a lot in some places really but there is room for improvement for sure. if you had a 2bar sensor i have a tuned bin that would have you running straight away when you get the charger on

the 2 bar map is built, now need to test it. don't see why I can't put a tee piece in the hose to na engine 1 bar map and if output is half the 1 bar output then all ok.

you can run on a 2 bar without the charger if needed but there is no real point tuning anything as it will need tuning when the charger goes on .do you have a 2 bar tune allready did you say.

sorry for confusion, must learn to be more specific. the 2 bar map is not a tune but a sensor I have made for the sc install and was wondering if anyone has a proven bench test for a map sensor. otherwise I will have to use my na engine.
