It easily spun the tyres in third before, and even more so now I'd imagine. Well done to Jim for extracting that sort of power from the beast.Your getting brilliant economy too. 8.7L/100kms on a trip IIRC? I've been itching to go for a spin but it hasn't happened... Rain, holidays, double demerits... You busy tomorrow Frank??? lol. I know, more rain and Bathurst... There's always next week I guess. Link to comment Share on other sites More sharing options...

How long ago were the rods changed, and how did the pistons look? I remember Ninka mentioning a few years back that his ba pistons let go at around 360rwkw? no drama's for you in this respect but!

Hers's an example where you can see the richer afr's on lower boost. http://www.fordxr6turbo.com/forum/index.php?showtopic=61665Having said this, I do not re-calibrate the speed density tables. In a nutshell I set the base fuel table to what I desire and adjust the injector high slope. Tunehouse are one of the best in the game so their calibrations would be more advanced than mine.

The tune is pretty good I've been messing around with it since I got VCM but am having a hard time improving on Jims work but also having fun learning.Just did a 2000km + trip and returned 9.1lt/100 which is pretty good for the power out put, about 500km of that was in Melb CBD.

I had initially set AFR's to 11.8 when tuning on the street, however when I jumped on the dyno I was seeing just over 11. I initially thought it was a loading difference between the dyno and street, however I went and logged load on the dyno and it's pretty much identical to what I'm seeing on the street. My boost does drop in the high rpm on the dyno compared to the street but that does not explain the mid RPM difference. After looking at some AFR data for different instruments the LM-2 did show leaner than actual AFR so it may just be a difference between instruments. Anyways just don't be alarmed if it's a little leaner than expected as you know you're working with a very good tune. Cheers and enjoy!edit....in saying power runs, I gather you're going on the dyno and not using your LM-2 AFR meter...whoops!!
