JC#79’s Nordic GTT (Updated pics)

Ok after another busy day oop in bonnie wee Scotland I have finally managed to free up some time to take pictures of the graphs from Friday's dyno runs & find the past runs done with GTT after the previous mapping session by another tuner (not setup on a dyno on the road instead).

After having issues with my ECU I decided to go in another direction with the engine management for the car. I am not suggesting the issue was related to the previous daughterboard so please let's keep this post on the facts...

After extensive research & glowing testimonials from others I trust who have used the equipment I decided to go with the now mature NIStune mapping software & daughterboard.

I contacted Pete from PMLS regarding the equipment needed to install the board but while investigating this option stumbled onto the work of FCTuning's Steve Sadler who has been supplying, fitting & tuning these boards for quite some time. Steve offered a very competative price for supply, fitting & mapping so I decided to go with that option as it would have worked out more expensive to have bought the board then paid for the mapping separately.

Due to the logistics with my car being north of the boarder once the board & base map were merged the board was sent up to Ant for installation. I won't bore you all with the intricate details but instead get on to the details you wanted to hear about.

Day of the Dyno began with me following Ant to Hypertech where a dyno tuning day had been planned with two P11's a pulsar & other cars all being tuned. This being the 1st time of me driving the car in almost 6 months I was nervous to be behind the wheel but this soon passed.

The base map did it's job & got the car to it's destination once all the prep had been carried out (remember preperation is the key to things going smoothly). Prior to setting off Ant fitted my new SARD fpr & gauge as per the recommendation by Steve, the improvement from the ebay jobbie was noticed immediately.

Now for the 2nd time that morning I looked as white as a sheep as once at the dyno all my fears about something going wrong had me worrying about having no car & failng in my quest to get GTT up & running properly. Ant commented on my expression & ensured he made sure I was sufficiently wound up over it...

The car was connected up to the dyno by Duncan the owner of Hypertech & we were now ready to let Steve work his magic. As he worked away with the engine in different stages of mapping I began to fret less & less as the time ticked on. The engine was singing & Steve was impressed with the build quality & made comment to Ant for all his quality work.

I didn't manage to take many pictures that came out clearly at all due to having forgotten my camera so images were taken with my iPhone.

Here are some images taken followed by the previous dyno results from the previous management system & map for comparrison (pictures are limited due to my needing to film the mapping at the request of Steve):












Previous runs:
Dyno Dynamics day of the original map






Dyno run after JF 2009:






As you can see from those graphs the fueling was far from ideal & the figure was indeed disappointing from a retrospective viewpoint.

Now do I reveal the new graphs or come back later to post them???

Ok I will sort it now so you all don't try & lynch me on mass:

Dyno run 20/08/10:

BHP @ flywheel


BHP @ wheels


Boost setting @ 1.2 bar


Torque - 347 ft lbs


So there you have it am I estatic you bet ya I am there are so many positives the engine has so much more to give Steve believes if I replace the 2.5" exhaust with a 3" I will get better results due the the restriction of the gases getting out of the manifold faster without putting as much strain on the turbo. He also stated he felt the boost could be raised as high as 1.5 bar but that he wasn't sure the gearbox or driveshafts could handle the additional power. This leaves me with a nice few options if I crave more power but honetly I am just happy to have the car properly setup and ready to be driven & enjoyed.

I hope this hasn't taken up too much of your time & can I just say a few thank you's to those who have helped me in the recent months with getting the car back on the road...

Gizz - Andy, thank you for getting my stricken car & taking it oop north you are a life saver & I owe ya big time.

Ant-Dat, you are a Legend my friend & by far one of the most talented if not the most talented folk I have ever had the fortune to have met & been helped by.

The car is in the final and your votes are very much needed, it's car no.9 GTT.
