Lost 42 horses: Wrong injector? Clogged? 2KD-FVT
Posted: Mon, 26 Jun 2023 7:29 +0000
Hi I've got a 2015 hilux, 200k km's on the clock, injector change at 155km.
Around that same time I changed something in the tyres, but felt slow since then. Blamed the tyre size.
Now I've gotten it on a dyno bank.
102hp at peak, 269Nm torque curve is looking ok.
expected 144hp and 343Nm...
Did also test without the MAF sensor fitted, same results.
Big question is what to do next:
- check exactly the type of injectors fitted, are there even different injectors for this engine at 100hp (no intercooler and no variable turbo I believe?)
- open up the full inlet system for a clean? (1 valve spotted with an inspection 40k km's ago didn't look that bad at first glance)
