Don't take offence if he doesn't reply for a few hours. He emailed me a while ago, and was just off to lunch.
By the time he staggers back, it'll probably be Thursday ;) Josh |
o.k anyone?
PLEASE |
Some info from IWOC:
The standard exhaust is extremely restrictive, consequently the ecu expects boost to climb at a very slow rate and is very slow to react to increases. If you fit a performance exhaust, then turbo spool up is in a different world and a lot of boost can be achieved before the standard boost control set up does anything about it. The reaction speed of the control system is controlled by small airflow restrictors in the piping between the turbo, wastegate and wastegate control solenoid. The smaller the holes, the longer it takes for any pressure changes to work through. By either opening out the size of these restrictors, or by replacing them with larger holed ones, the reaction times can be altered to match the new rapid spool up. This gives much more accurate boost control and prevents overshoot. |
