Boost problems
Boost problems
Right here we go ,iv had bost issues for a long time tried many diffrent things and im looking for some new ideas.
It used to just boost to 0.5 bar and i always thought it was in limp home mode,but what i found ou if i pushed the car hard it would go above 0.5 but not the way its supposed to.But now what iv found out if i drive the car for a while in 5th gear a say 70 to 80 mph it will boost fine for a while also when i reset the ecu it will boost normal for a short time.

The ECU is the original std one.
The turbo is a TD05 16g top entry Std fit, it was replaced with another TD05 std turbo and it made little difference, the original turbo from when he first brought it is currently fitted, the ebay one in the garage
The problem car is a Jap import and so was the car from which the replacement engine was sourced. They are/were both Phase 1 engines. When in the car before it crashed at the ring, it was running fine.
It has been paralled using the std FPR so will not need a reset of the ecu as it still see's the same values etc.
It doea have a decat and an induction kit, but before it blew up originally it was running ok on the same set up.
We have tried another boost solenoid (from my V4 Sti) and it was still the same, like Steve said, it has no restrictor pill fitted, it didn't have one to start with.
Both the manifold gaskets have been changed for new ones (Exhaust and inlet) so we are content we have no leaks from either of those.
Boost pipe work looks ok, no leaks could be seen, not sure on the MAF though, it may be the route cause of his initial problem as it's the same one that was fitted when the engine gave up.
What else do you think then gents?

fit a pill inline is what id do first, your ecu is probably ok at first and when u give it the beans your maybe getting a boost spike and the ecu is reverting back to limp mode,
just a idea but for a few pence it has to be worth a try.

You can buy the hose and the pill from a dealer for about 25 quid.
