Thanks to everyone for the quick responses!

Much appreciated.

All being well there'll be another OBD Tuner supercharged vx around within a few weeks!

Much better than a totally standard car on OEM map, by the look/sound of it.

It's loads better then it was standard. I've been cruising for towns in 5th gear which I could never do before.

I'm going to have to sort this as currently mine just splutters at low revs in high gears....

Chuffed there seems to be a fix for it as it is a bit disconcerting 

[fezzasus]

The spluttering is because the CS map overfuels over part throttle.

We are talking about the dutch software here though not a CS map - Unless it's a common thing..?

 

Whatever the cause, if Peter is now in a postion to help improve, I'm a happy bunny

[CHILL Gone DUTCH]

This is mainly for after market cams on the Dutch software which some people get cam overlap causing the car to splutter under 2000 ish rpm

Oh, I thought you meant you are still using a CS map.

 

I'll soon be running stage 2 comp cams on a 2.0 so it'll be a good test of how good the control is.

[CHILL Gone DUTCH]

You should see close to 300bhp tom

sounds like tip-in problem

[Exmantaa]

How is the idle now with these latest OBD mapping improvements? Steady?

 

I finished my 2.0 with Harrop & ZZP st2 cams this week and the idle (~875) and low load driving seem pretty good sofar But I'm running an LSJ ecu and now playing with injector settings.

 

[oakmere]

These changes don't improve the idle settings. They make a big improvement to tractability at low rpm driving with longer duration cams.

[CHILL Gone DUTCH]

Peter actually found the new settings for low rpm while trying to sort the idle issue I'm interested in how good idle could be mine sounds a little like a muscle car on tick over but I expected this with the cams

[slindborg]

yep, tip in and tip out are the two hardest things to actually calibrate properly :s

The Transient Ignition Retard function is designed to introduce ignition retard during transient conditions.

 

Transient conditions are identified by a fast change in Throttle Position (TPS) or Manifold Absolute Pressure (MAP). Ignition is retarded depending on the rate of change of TPS or MAP, then held retarded for a particular number of engine cycles.
