HI ALL IVE GOT A 2001 BUGEYE AN IT DOESNT SEEM TO BOOST PROPLY SOMETIMES IT BOOSTS BUT NOT TILL ABOUT 5000 RPM THEN OTHER TIMES ITS BOOSTING UP THEN DROPS OFF THEN BOOSTS UP AGAIN HAS ANYONE EVER HAD THIS PROBLEM BEFORE COZ ITS DOING MY HEAD IN THANKS

 

be very interesting to hear what it could be as i dont think mines boosting as it should do bugeye

 

Well ive had it on a 2002sti whereby if i ran it at motorway speeds (4th,5th or 6th gear) so not rev dependant, cruising with light throttle for a min or two then accelerated hard i could only get half boost unless i came off the throttle and re applied.

It was at the time looked at by Andyf, Who could clearly see that the boost was as i described, but couldnt work out why it did this. He loaded a new map and all has been good since, That was maybe 5 years ago now.

 

ive just text the fella that usually does my mapping for me to see what he thinks it is so if he gets back to me with a reply i will let you know whats yours doing coz mine is all over the place and its doing my head in but im selling it and i want it right before i sell it

 

could it be the boost solenoid needs cleaning

 

thats what i thought but tried that an still no change maybe it f**ked

 

can y pm me if you find out whats causing it thanx

 

yeah will do mate

 

Any more ideas 2002 sti does exact same as Turbotits , its so annoying .????????????

Turbotits

Legend has it the bug Denso ECU has a drive by noise reg bypass code that during testing limits revs and boost (hence noise). The test involves driving on constant throttle then accellerating. The ECU picks this up during "normal" driving and thinks it's being tested for noise and won't boost.

So the legend goes LOL

Is there any way to stop it ??????
