OVERBOOSTING? technical help please

[lescazscoob]

my car has had a few teething problems since i got it and i have been told it is overboosting the car drives fine if you gradually feed in the power but if you put the foot to the floor it seems spluttery and cuts all power after 5000ish rpm followed by a bit of popping from the exhaust.

i have been told to replace the boost control solenoid but am unsure whether this is the problem or not any light on the subject would be a very big help to me.

cheers

What spec - full decat, standard ecu etc. etc.?

Always hard to say here, but could also be a dodgy fuel pump!

I had that on my Wagon... I fitted a Dawes Device and took the control away from the car, worked fine after that. What I would say is, try and set it up on a coooold night so that its got a built in margin for error on warmer days.

I cant help you with the Boost/Fuel cut limit on your car though. My wagon was 1.2bar, then you hit the windscreen when it hit the wall. []

Cheers,

As Grant says.

 

I have a brand new manual boost controller here if you want it. £15 delivered.

Manual controller will give you the control you require.

[lescazscoob]

[] I aim to please.

 

The MBC gives better boost control than standard, with the benefits of it being so much easier and quicker to clean, when the time comes.

You don't need to set the boost higher than standard either, so it's not as though you NEED loads of gauges tomake sure it's ok. Just so long as you have a boost gauge, just to make to you get it set bang on standard, or a touch more if you the extra gauges.

 

PM me if you do want it. Instructions supplied and if you get stuck, i'll label the pipework so you can't go wrong when fitting it.

I touch goats drb5 cheers guys for the help will see if this works and update post to let you know.

one last question ive been offered a p1 boost solenoid will this fit my car?

cheers

[drb5]

Replied Les.

 

It won't fit, as you need a 3 port solenoid and the P1 uses a 2 port.

Check all your vac hoses round the turbo area for splits, mine was donig the same when i first got it and it turned out to be a 2" long piece of vac hose with a small split only visable when i  flexed the hose, changed it for a bit silicon and as good as new. worth a look ! []

[lescazscoob]

im going out to the driveway in 5 minutes to check over all vacum hoses going to fit a boost controller from drb5 and a b oost gauge when i get one hopefully this will rectify it.

cheers
