Thanks Pete, sounds good. As for warranty issues... I think you could replace the entire engine with a TDV8 and I know of one dealer that wouldn't realise. I don't think they even know how to lift the bonnet! About all they seem to be good at is not doing anything. Oh and any word on a Mac OS X interface for the BAS unit?? 110 2.4TDCi 110 300Tdi

Yes you are probabally correct, some dealers may not even realise lol..
re the real MAC software, I do keep asking the software creators for a propper mac version but ive nothing as yet 
PeterTD4, ive used it on my Win7 32bit in the office to test it and all was ok on the short tests i did. Pete |

Thanks for the speedy service, Pete. I would have uploaded the new remap tonight, except my local village garage managed to start on my damper and spring swap at 4pm, meaning I wasted an entire day, and can't pick the 110 up until tomorrow.
Anyway, just wondering....I've generally (like most others) been very happy with my BAS remap so far. Much improved driveability and smoothness. And not being limited to 86mph is good for the odd motorway blast (in Germany of course, officer...  )
Only 'glitches' are a noticeable flat spot when accelerating in third gear and fourth gear, on slight hills, sometimes. almost feels like the engine is 'pulling back' slightly. Like it's not breathing correctly. Only very subtle. Could this have been the EGR Valve? Just curious.

Hi
In theory yes any flat spot felt could be egr related for sure but some other things are a possibile cause also. The egr as you will see in a picture below which is just one many of the maps related, its open depending on rpm and demanded torque. Ive removed the demanded torque scale from the picture for my tuning security but you can see the rpm scale and the output of the egr in % shown in the main map in blue. As you will see when the car it at a low rpm and low demanded torque request "Left side=low demand Right side=High demand" the egr valve is open a lot EG @ 800rpm and 0 demanded torque its 85% open. As you pedal/accellerate the car and demand more torque and the revs build the egr should start to close as you see from the map, and be fully closed in this maps case at 3500rpm. In some cases the actuation speed V the speed you demand torque and the demanded ammount especially when tuned for more lower down torque or worked hard in gears means the weak "in my option" valve can not meet demand the car needs. Their is more than one map for the egr valves depending on the cars situation at the time and a few more that are related this is just a example to try and put reasoning behind what we have found on many cars egr valves. As seen in the picture the % of valve open drops of quite rapidly at in this case from 3000rpm and some as soon as 2800, this closure is also felt in some cases as a surge or flat spot as the gas is re routed into the turbo when the egr is shutting or shut. As with most cars, generally egr blanking does improve driveability and in some cases economy which is why so many people blank them. and of course when they fail open its a costly repair in a lot of cases which is parlty one of the reasons we looked hard to create a puma egr soloution that was not mechaniclly intrusive and could in most cases be delt with electronicly. So yes, it may help you or at least i hope it does lol. As always we will be continuning to make updates and changes to this soloution amongst others we are working on as we do with all our tuning, so any updates will be sent to customers that we feel will help them further. We dont do fit and forget, we always try to better what we have already done which is why the BAS interface is so well suited to what we do

Cheers for the detailed (and speedy) reply, Pete.
Since the flat spot/hesitation I mentioned is, in one instance, infinitely repeatable - Happens in the same place on the same road, every day (on my way to drop my son off at school!), I should, tomorrow afternoon, be able to say for sure whether it was the EGR valve causing this particular phenomenon.... Fingers crossed.

Hi Pete,
Well, got the 110 back from the local garage (complete with greasy fingerprints all over interior, and oil mark on seat...  ), and am off later on to pick up my son, so will give you a call afterwards with the verdict on the remap.
Have now uploaded the remap, but thought I'd scan for DTCs before I did. Got the following, which seem interesting: P0404 P0100 P0234 P1103 P1402 Must admit, hadn't expected a 4 month old vehicle to have so many diagnostic codes up, but it is a Land Rover... If I'm right, o404 an 1402 are EGR related? Hmmm...

szracer, the following will discript the codes for you.
P0404 - Exhaust gas recirculation control - circuit range/performance P0100 - Air flow meter sensor malfunction - mass air flow 5 supply voltage faulty P0234 - Turbo/supercharger overboost condition P1103 - Mass air flow sensor in range but higher than expected P1402 - Exhaust gas recirculation - metering orifice restricted/valve position sensor circuit To be honest i would not worry to much about any of the above, unless the car is having problems. The BAS interface reads tested and non tested DTC's in one menu which can make for confusion or un needed worry sometimes. and lead you to beleive you have a problem when you dont. Pete |

info for all who are interested.
Ive been working on a 2007 110 today that had a permanent engine fault. Luckley for me the fault was related to the egr valve and the air flow meter. After some tests and monitoring the live data for EGR position when standard i found as id expect it open between 45 and 65% ish, i then applied the egr shut to the car and sure eniough the light went out and didnt come back
However after the shut file was added we could very clearly see from the live that the valve was closed a lot more that standard helping with the driveability considerbly as we would expect, but for some reason at times it was not shutting correclty as we have seen on our test cars and was staying open slighlty, sometimes upto 15-20% at idle , mostly this cars valve was doing as we damamded from it in the shut file but their is in this case something obviousley keeping it from fully closing even though we demand it to.
We will continue the developement on this car as its a perfect car to do it on with it been faulty already, and any EGR updates available will be given to the people who have this now as a free upgrade to what they have now. On driving the car with the new shut file it was clearly better than with just the faulty valve which is our aim, i think in this case their is room for even more improvement and as said i will pass that on to my customers when its made.

Spoken to Pete today after my first EGR remap run, and have swapped some emails. Here's a synopsis:
The flat spot that I mentioned, seems to have gone (or is certainly a lot better) - And as Pete suggested, the car is still adjusting to the remap, so things will settle down further after some more runs.
The car feels much smoother to drive. Ironically, this makes it a tad less 'exciting' to drive - But think that's more a case of me learning to re-learn a copule of the gearshift points. Power delivery feels better without the hesitations. A few more DTCs than before - But not too worried. Looking forward to even more refinements going forward
