Default VE autotune in tuner studio

Yesterday someone from a local forum installed my megasquirt build. I bought it from reverents group buy.

Cars a 1990 Jap import 1.6 m45 supercharged running standard boost, intercooler and dual throttle bodies.

I ran auto tune for a while yesterday after it was all set up and it was great however, I found that when getting near the red line it feels as though there is not enough fuel going in. As I am relatively new to tuning I don't want to start putting bigger numbers in for obvious reasons. My question is, will the VE auto tune facility correct this and eventually add the fuel in for me or do I need to adjust something?

I know I have lots of tuning to do yet and its all a learning curve so bare with me

I was going to say "wow, you got it so many months ago and you only installed it a few days ago?", but then I remember the number of parts sitting in my own garage waiting to be installed in my new engine...

Enjoy your unit. To answer your question, you are way better adding fuel beforehands, and then let VE analyze remove the excess fuel, than running lean in boost and trying to add afterwards.

Great, thanks reverant. Can I just clarify are the boosted areas the red parts of the table?

I put off installing the megasquirt because of lack of knowledge and still don't have that much now. Once I have found out what areas of the table are boosted I will add more numbers. How long would you recomend running the autotune for? I know I need to change it from medium to hard to extra hard after a while to get the best from it but at the moment I am just tuning every time I drive the car.

In fact this is my VE map so far... Only had about an hour and a half worth of auto tune.

I'm not seeing anything attached. Personally, I'm not running VE analyze live in boost when tuning. But then again, I've been tuning my own car for 4 years without it, so I do have the experiece to do it. I would start with easy to add/subtract fuel quickly to get you there without running lean. Then increase to normal, hard, etc, until it adds/removes 1 point of fuel but stays there more or less.

Ok thanks for the advice Reverant, I will give it a go tomorrow before I set off to work. I will be running the autotune on the way to and from work, its not much but every little helps I guess (my journey is about 35 minutes 29 miles). I will change it to easy to start. Then maybe tuesday I will change it back to medium.

Well I have learnt alsorts already today. Firstly, that I need to scale my tables properly. I mean when will an m45 charger ever put out 300KPA haha.

This is a slow learning process but its starting to happen. I have just re-scaled the values of my VE table and of my target AFRs.

This is what my current AFR table looks like (going from advice from a friend) although I'm still not entirly sure why the red ones are so lean.

Not to be confusing, but your rpm's look scaled funny. I would lose the 500 and 1100 block and move them up higher for more control up high.

Ok, I did wonder why the 500 was there, thought it was just something that was meant to be there. So leave the 800 but move it to the first coloumn?
