2007-09-25 The boost gauge shows about 0.5 bar (7 psi) vacuum at idle and when driving the pressure values are between -0.7 bar (-10 psi) and +0.7 bar (+10 psi). The wastegate should be rated 0.4 bars (6 psi) so maybe the wastegate won't open all the way? All the same the car is like newborn and the acceleration is satisfying. In the city the car works as good as before so I can crawl in the que with it. Tuning and testing continues... There is problem with the rubber hose from the air meter to the idle valve which flies off at high boost. I must see how I can attach it better.

here is the problematic hose and it's attachment. Sergey from mersuforum.net gave me some advice about the problem, must try them out.

Still problems with knock. Dropped the ignition max advance to 17 degrees (EZL KAT pos 6). The response off boost is not so good because if the ignition setting. The EHA base mechanical mixture value is 0,90 (AFR = 13.2). The programmable target lambda is also 0.90.

Beecause of the small base advance the engine is lazy and thirsty at cruise speed. I have considered building a programmable ignition controller from Jaycarin Electronic kits KC 5442, KC 5443 ja KC 5386. They are introduced in the Silicon Chip web magazine . One possibility is a Megasquirt with ignition only. |
