afaik he only has happy customers. Just with lot's of questions

I'm a little underwhelmed with it, since fitting it, if I'm honest. Apart from the cold running improvements and the flexibility of changing components at will, the whole car feels a bit lethargic when compared with the original Courtenay map and it has a nasty occasional misfire type thing (a little like you get with a Scangauge connected) when making progress and shifting quickly between gears. Hadn't encountered the misfire until I applied a different map from Peter to better handle aftermarket cams.

When you say lethargic You mean less keen ?? I think this is actually down to the smoother maps Have you played with ignition etc Also have you got a wideband fitted and checked the AFR

Yes, less keen in the mid-range and just generally a bit slower all round. Not really, Peter has mostly done the changes on the ignition side of things. Yes, wideband fitted and appears to be working. AFR's look believable, they go rich when I press the accelerator and go lean when I lift off and seem to average out at the commanded AFR. I never had the problems that some of you have had with the Courtenay's map but I had many many many maps done to make it as smooth and responsive as possible.

I think there is quite a lot of people who have not exploited the software to its maximum especially around the ignition area To get the most out of the cars I must admit also when I started to use the software I was a little scared with what was going on I didn't really want to change things because of the same reason but this didn't stop me exploring different areas in the software Some might call me a fiddler But I do think it has taught me a lot more understanding of maximising the potential of the software

You need a harrop techie

You will still need to become a fiddler To get the most out of it

We are sheep Chris, and need to be guided to deviate from the built in learning options, and see the true potential of what it can do, based on examples.

 

Maybe make shitloads of screenshot and explanation next time you work with someone on smoothing?

I think you answered your own statement then TB.. For those of us with crappy part-throttle, stuttery delivery, and a very after-market feel to the CS mapping, I'm sure it would be a large improvement..

 

Can you perhaps play with the throttle responsiveness / ramp settings to give you back some of the character..?

Well, I've done many many mapping sessions and many tanks of fuel with this (even discounting the fcukups I've made losing various "learning" sessions) and remain to be convinced it's improved anything, other than the first 30 seconds after a cold startup and being able to change the injectors and decrease the rev limit, without a trip to Norfolk. I didn't have a random violent misfire before either. I could change the throttle map (currently OEM response curve) but that would just be hiding the underlying feeling of lethargy. I can always drive the Audi if I want 100% throttle at 10% pedal movement.

That's what I'm desperate to avoid.

I think people in general are underestimating the time you have to put in to the software to get the most out of it Peter is there for help and guidance but in reality he can't do it all for you. If you know and done the work on the software before it still takes time, but when you do it for the first time it takes 10 times longer, because everyone has wished they had saved a particular file before they had stalled the car or forgot to make the file permanent and lost all the information when they turn the ignition off going back to where they started It's all part of the learning and gives a good insight for the none taught in mapping a car As Nick said somebody who has mapped a car before will have a significant advantage as they have idea of where and what things are and where they want them to be

Yea Bills car got good figures from it

[CHILL Gone DUTCH]

Yep the best figures so far 

 

until you get the 2.7 pulley on the go 

 

i have a small pulley in the garage (2.8)  and after the track day season is over, im tempted to stick it on and see how it goes,

 

but i have to admit the 3.1 pulley i am currently using is more than enough for me at the moment

Hey Dutch software users, I am copying my feedback from Obdtuner's forum here: http://www.obdtuner....c.php?f=8&t=322

 

Reading recent interaction here, I reckon also that I only scrape the surface of the capabilities of the software but having already achieved this result is satisfying. I have a wideband sensor, not fitted yet. Is this the absolute first requirement in order to go further ?

 

Soft requirements are also finding the time (a learning session can take long) and having a decent Windows laptop (only have a netbook for this application and it is a nightmare to use, a linux or MacOS build would be awesome, but that is another story)

 

 

This is a simple message to provide feedback on OBDTUNER.

 

After a very long installation process, not due to OBTUNER but rather to the condition of the car that was out of hibernation. It suffered from a failed catalyst, that prevented it from revving to more than 3000 rpm.

 

The car is now transformed from the previous mapping it had. I would like to thank Peter for the tremendous amount of work and great support he can provide. The throttle is nice and smooth, no hiccups. It gained a lot of drivability with is the main reason I prefer supercharger to turbos.

 

Highly recommended !

Wideband sensor is not required, but it can speed up the full throttle calibration process, according to Peter.

Try a few small changes to the throttle map it can totally change how the car feels. The CS map will not of had the straight line relationship as the std OBD Tuner map dose.
