Hi all,
So I have a bit of a problem when setting off, with kangarooing in first, I think I have narrowed down the options to translation, but wanted to canvas option...
So History: The Landy has been remapped by alive, and this is when the problem become more apparent... I think the increase torque has uncovered the problem. I've chatted with Gary about the map and he's happy with the parameters set, and I have also done some diagnostics which I feel confirm its not engine:
- MAF: tested and reading well - 56kg/hr at idle
- MAP: cleaned tested and working well
- CPS: cleaned and no issues, engine runs smooth, no lumpiness or surging etc..
- TPS: all voltages reading well - both tracks & constant.
I have had the transfer box high/low switch and jumped the plug to put it into "low map" and you can feel the difference in the throttle response, with much slower input and throttle response, which has actually significantly improved the issue, but obviously has only masked the problem rather than solved it.
Overall the Land Rover drives well, with nothing to "note" on the engine... the only thing is a "crack" when coming off the accelerator, which is what is pointing me towards transmission/ drive train. It sounds like it is coming from around front passenger side. Engine mount? or drive shaft?
So before I start stripping things down, and chasing problems any advice/ thoughts on where to start/ look for/ test is warmly welcome.
