Being back to the same dyno, no graph yet, but in short the X51 map has cured the lean fuel issue.

Before WOT was 14.7 AFR upto 6000rpm with generic softronic map.
Now WOT is 12.55 AFR throughout the whole rev range with X51 softronic map.

In short now the car is running a little rich, but nothing that would cause any damage such as bore wash. But it is robbing a little power 4000rpm upwards.

Also the car gained very healthy sub 2500rpm with X51 map, no doubt because its getting fuel, hence the improves responsiveness I felt. There is a slight torque loss at 2500-3000rpm due to the flap in the vario ram being open to simulate the X51 car, for X51 map, but nothing noticeable by butt dyno.

I've emailed Scott asking if he can alter my tune to hopefully aim us towards around 13.3 - 13.5 AFR wise, this should result in best power/economy and is a safe target on an NA car.

This does however prove that those of you with X51 air boxes on stock map or regular softronic map are running very lean, which is dangerous to your engines. I'd advice you contact Scott for X51 map as it is much safer and hopefully now with a minor tweak to put a little less fuel in it shall also make more power too. Remember he does custom maps like he has for me but does charge.


My plan is when I get a tweaked map from Scott is to head back to the dyno again and do two runs:-

Run 1: Stock airbox with resonator removed and BMC filter, with regular softronic map, but with 82mm throttle body & plenum - As I believe this will make very good power in mid-range and top-end, as stock airbox flows enough and fuelling shall be spot on.

Run 2: X51 airbox with BMC filters, with Softronic X51 mapped with a little less fuel hopefully along with 82mm throttle body and plenum, so we can compare the two like for like.


I think due to how our engines flow air, that on a dyno the X51 air box probably gives no more power at all, ON A DYNO. But on the road due to having cold air rammed down two inlets, I think it does help a bit, plus it sounds amazing and looks superb!

So in short for X51 airbox owners, the softronic X51 map in its present state gives:-
- Resolves lean WOT issue, but is a little rich now at WOT.
- Improves low-down throttle response/torque
- Margin torque loss just before 3000rpm due to vario ram flap being always open to simulate X51 intake design
- Slight power loss 4000-7500rpm

Well worth it though for safety of your engine, but hopefully Scott will modify the map to take a little fuel out which should mean it makes same/more power 4000rpm upwards, making it spot on.

Sorry for lack of updates, I have a new tune from Scott which should give a circa 13.5 AFR, did a track event yesterday and car was fine, did my best laps ever.

I shall be heading back to dyno hopefully in couple weeks to see if this new tune file has the AFR better and helps with power. Shall also put stock tune and air box back on just for comparison.

As to the cost of the tune, that is private between me and Scott, but once I've checked the AFR on this latest tune file update and if it works. I am sure Scott will be willing to sort out any potential customers.

Even more impressive I went up against a 997.2 GT3 RS on two occasions and passed him, though it was hard work.

Thanks

The Op had made mention of the faults via email yet there had been no reason as to why he would get these new faults from the changes that had been made and we received no further info. These faults can happen from other reasons such as grounding and or power supply etc. Softronic had been working with the Op on expectations of information being sent to us and not on forums as we have not charged him as of now for any work provided. Softronic does require factual info to be sent to us as requested to further analyze any file for further adjustments. All work that has been done has been in fact custom tuning based on the Op's info . Softronic has asked for other info that has not been available yet we have worked on what we have received. The last file has been set to what the Op requested in AFR's. Im sure we can get what he or any other owner requests on a custom tune done.
