ECU Flash

[anpato]

I was wondering if anyone could explain to me what would be the best parameters to adjust to slightly raise boost levels im talking 2-3 psi safely without messing around with too many other parameters.

Boost target...
But then you gotta make sure your hitting your Max Waste Gate Duty.
But at 2-3 PSI you might be knocking.... so then double check your Primary Open Loop Fueling and richen up if needed. If that doesn't work... Check your Base Timing and Knock Correction Advance Max.

Sound easy enough man? Good! Try not to blow up your engine man!

Simple enough, ive been messing around with ecuflash all day so im getting pretty comfortable with it.

It doesn't work this way. You don't just "raise boost" to make power. There's a reason the car targets a specific boost pressure.

I understand that, I'm trying to learn efi tuning anf boost values seem like the easiest to mess with to learn.

There's a lot of other tables that need to be modified in order to properly raise the boost.

Yeah I know man, thats what I was trying to hint at

Wut?

Your boost target map will raise boost a bit, but if you are hitting your max WGDC... well... you aren't gonna get any more boost regardless of your target boost map.

I wouldn't add any fuel to a stock car map. I'd just cut timing back.


anpato - if you have to ask that question, you should do a lot more reading first. I have no issue with people tuning there cars - assuming they understand what they are doing. Are you familiar with wgdc at all? any idea how the boost control system works?

Even then, you are relying on your wgdc corrections to get you to the boost needed. They do not always extend to the max wastegate duty.

Thank for that =)

I'm not saying that, what I originally posted was not what I originally meant.

The problem is that someone unfamiliar with internal combustion engines and EFI tuning could read your post and believe that is all that needs to be modified and could end up damaging their car. Case in point, the reply just after yours:

This isn't something you pick up in a day, week, or a month. There are months of reading and knowledge base building needing to be done before you start tinkering, if you want to do it safely.

Fix'd.

This. I'm very rapid on the uptake of technical information, but tuning my car has been a project 3 years in the works. Changing parameters without a COMPLETE understanding of the implications may result in a 1.5 tonne paperweight on which you still owe $25k.
