hey, it works great on my car!

if you don't use correction then completely ignore boost error, BDE, boost adder, etc. You'll only be using the WGDC to set boost for each gear at each rpm. You can then use the MAF vs IAT (sic : I meant to say WGDC vs IAT) compensation to adjust for different weather conditions.

 

without running a BEC how plausible is it to run 100% WGDC during spool up?

MAF vs IAT.. how does that help?

 

Very plausible; here's my WGDC table



Just don't go too aggressive to minimize overboosting at spoolup and you shouldn't have any trouble.

Dunno why I said MAF vs IAT, I meant WGDC vs IAT. As intake air temp gets colder, the turbo will spool quite a bit more easily, so you want to use that table to lower WGDC when it's colder to have the same boost.

 

so i decided to try and find my boost error at a BDE value of "20" for every cell... and this is what i found....


i dropped my boost adder to '11.1' because my WGDC at anything of 67% was over boosting... with a BDE 'psi' table of 20 at every value... according to my logs... OMNI Map = 21.7457 psi... Boost Error = -0.0022... RPM = 4062.. my WGDC is 67% at every value...

If the ECU just wants a boost error of '0' can i set my BDE 'psi' curve to 20 with an adder of 11.1 (even though my atmospheric pressure is about 14.5 in Virginia Beach) @ peak of ~4000 RPM.. {BDE'psi' = 20 @ 4000 RPM and every RPM below} and then taper down according to my current boost curve.. utilizing mr fred's BEC Table provided here...

Yes you can totally do that. There's nothing that says that boost adder has to = atmospheric pressure, it's just that it makes it easier to read your BDE table when it is. In your case it'll have the same effect though; whatever you put into your BDE table will be the target boost curve for the ECU.

 

as far as setting the WGDC.. i can now run 100% WGDC right? With the BEC table engaged it will automatically correct the WGDC?

or is it safer to go 100% during spool up and cut it back to about 67% through my peak boost values and even lower as the motor approaches redline?

 

NO you can't run WGDC at 100% at all times. The car still needs the correct WGDC curve that will get it close to it's desired boost curve. The BEC is only for minor corrections, not all-out boost control.

 

Exactly. Just use a MBC.

(and this is coming from the guy that wrote the ECU boost how -to's...)

 

I have no regrets moving from my MBC to ecu-controlled boost. To each their own

 

been a while... bump.

any SD rom for 90550001 v7?????

 

need some help, please.

just flashed my E7 JDM with 90550701, just changed the immobilizer code.
the boost dont go past 0,8bar.
its probably something simple but ive checked and cant see it.

 

Did you set up your boost tables? By default it will only allow it to boost to WG pressure.

 

No I did not set them up.
I didnt needed to do with v5.10.
Is it hard to do?
