Supercheap Auto charge $25 to put a scan tool on it and clear the error code. Mazda dealers in Chch charged over $100 and wouldn't/couldn't tell me what the problem was. Independent auto sparky sorted me out with that bit of advice.
Rubber intercooler pipe split twice. Replaced it both sides with an aftermarket hard pipe kit that was cheaper than one OEM replacement rubber pipe. Had Diesel Tune NZ do a remap for me over 100k ago. Excellent performance upgrade for the $1200 it cost. Then I fitted an electronic throttle controller and that was the best $300 spent. What you think is turbo lag is engineered slow throttle response to help fuel efficiency. With the next ute I'd do the throttle controller first and possibly not worry about the ecu remap.
Also suspension, bar work, snorkel etc etc... none of which helped how much fuel it drinks.

I dunno, that intercooler pipe issue is something I've never heard happen on a manual box one - no idea why that would be though. Yes on the throttle lag, but again it is much worse on the auto's. the throttle controller does less than the remap on the manuals, but you're rolling the dice on the dual mass flywheel with the manual!

I have a bluetooth dongle, can read/clear fault codes and also live-report with gauges on most things the ECU does. One thing I've noticed though is that the dongle seems to turn the limp mode and error coding off which is weird. You can see the issue that is causing the coding and associated limp mode on the gauges clear as, but while you can see it the ECU doesn't drop the limp mode or codes. Must be something in the software when the OBDII port is active.
