Strange Boost problem om FD
After instaling an upgraded ECU from Re-Amemiya wich is supposed to boost 1.1 kg at the primerary turbo and 1.0 kg at the secondary turbo. WE got some problems. First off it would only boost about 0.75kg on pri turbo and 0.8 in third and 0.9 in fourth gear on the sec turbo.
Then after fideling abit nothing happend, and i sendt the guy back home with the car. When he came back to me today the primerary turbo did only give about 0.1kg of boost but at 4500 rpm it came on like it had a non sequential turbo setup. It boosted at 0.9 kg. It did go up from 0.5 to 0.9 at about 5500 rpm.
Then i changed the one way valve to teh pressure chamber and checked the other vacum lines, and it boosted on the pri turbo. But did not start to build boost untill 3500 rpm, and only about 0.65-0.7kg of boost. And 0.8 in third and 0.9 in fourth gear on the sec turbo.
I spoke to Steve at Gotham Racing and he told me it could be a cracked turbo. In the exhaust housing.
What do u guys think?
