Unfortunately not Mark.
Anyway, I went back for another go yesterday and made some progress. The day wasn't without its problems but was much more successful than the first time.
The first issue was too much restriction in the waste gate dump pipe. Rather than run an open screamer pipe I fitted a Supertrapp muffler to the end of it. this was after a fair bit of research into what other people were doing, this seamed the best option. After the first run we found too much restriction in this pipe so had to remove the Supertrapp.
Second issue was controlling boost. The turbo wanted to make boost quickly and lots of it. I wanted to limit it and feed it in over a longer period of time. It took quite a long time to remove the boost oscillations at the start of boost control.
The third issue that was intermittent throughout the day was a misfire. It was only evident as we started to add boost but wasn't predictable. Frist thing we did was the obvious which was close the plug gaps up and that seamed to fix it for a little while. The next was increase the coil change time and that initially had an effect but then went back to misfiring. Then tried reducing the coil charge time which also initially fixed it. We now suspect its all down to the ignitor getting too hot. The ECU doesn't need the ignitor so I'll probably remove it and just fire the coils from the ECU.
At the end of the day, although we didn't get to do a top end power run, we did setup 4 low to medium power setting that I can switch between on the fly with a rotary switch. Starting with a low power, low boost, flat curve, 350hp setting, up to a 1.5bar 487hp 414ftlb setting I can have a bit of fun with. Also fixed a few other issues I had with starting and low rev pull aways. It was a long day and by 10:30 last night we had all had enough so the rest can be done another day.
