Morning all,

Not so long ago I installed a boost gauge in my STI to see what it's running at. After looking on here and seeing people running 0.9 - 1.1 safely on a classic I thought that my measly 0.7 is not enough. I knew the ECU has an ESL daughterboard on it but after speaking to Richard at ZEN he told me it's a "static" daughterboard and not mappable live, so I thought I'd do some research on my ecu and see why the boost is so low.

Here's what I found - http://www.southeastscoobies.co.uk/v...hread.php?t=78

I have a V5 ecu which is out of a wagon and only running 10.5 psi/0.7bar but the ecu must of been mapped with the ESL to run the mods I have - front mount, turbo back exhaust, TD05, HKS mushroom filter, walbro ect.

So my questions are

1. Can I buy an ECU that's right for my car and use the current ESL board so it knows my mods?

2. Can I buy the right ECU that's already mapped for the same mods as mine and just plug it in?

3. Should I just keep the ECU I have and just get an ESL live daughterboard put in?

Many thanks

James

I know mate, something needs to be done!

it will need mapping if the boost is turned up, otherwise the fueling will be out and could cause damage if running lean.

Sounds all wrong to me bro, with those mods, lose that Wrx wagon ecu, get a Z4 have it live mapped you should be at a comfy 1bar with those mods, don't need anymore boost than that really,

Did u buy the car with all the mods done?

Yes mate, all the mods were on and all set up by the previous owner who I trust as he's my mates boss and was a mechanic for a Subaru specialist for about 9 years. The car is running fine with the mods due to the ESL it has, it's just running low boost and I'm starting to get bored of the power

My boost gauge sits a 0.7 90% of the time when I have my foot to the floor. Maybe I should get it on a rolling road and see what it's running.

The static ESL board wont have been mapped for any mods so don't use it on a modified car.
