do you need a re map if you have a nos system fitted or is it a totally additional/stand alone thing?

what are the different set ups? wet/dry?

Wether you need a remap depends on what you are doing with it, what do you have in mind, ie what sort of gains are you looking for and on what spec engine?

Dry systems fall into 3 categories:
1) they rely on the ecu to provide more fuel my being programmed for the nitrous system, potentially ok but has a few hazzards

2) rely on the fuel pressure regulator being "fooled" into adding more fuel by upping the pressure, VERY dangerous dont go near it

3) dont add any more fuel at all, this is about as useful as driving your car into a river.




So unless its a very specialist application you will be looking for a wet bascially mate.



Give me some more details about the car and i can give you more details about nitrousing it

stage 3 cosworth, (fast enough on the road for me LOL!)
but when you go to the pod/0-60 would be nice to have a little edge!

what advantages does it have on a turbo engine over n.a. if any?

For anything up to 100bhp (progressively controlled) on a stage 3 YB you will typically NOT need a remap, if anything you could map on a little MORE ignition advance to chase down every last horsepower but i wouldnt advise it as the gains are minimal and you are eating into your safety margins

The big advantage is that the nitrous is cold, VERY cold, so if your intercooler is a bit average or its a hot day, you get big gains from the temp drop as well as from the nitrous itself potentially.

Other advantage is that it will spool the turbo up much more quickly, it works REALLY well as antilag, although obviously more so on a bigger turbo where there is more lag in the first place.

thanks chip,

am i right in thinking there is a plug in the loom that allows the ignition to advance/retard why is it there?

Im not the best person to ask, Stu is, as i dont know about all the different L1/L6/L8 etc and what the options are on each.

But certainly there are retard wires in the loom, that can be confgured as part of the remap and then when grounded (think its grounded anyway from memory, Stu can clarify no doubt!) tehy take off a fixed amount of advance, ie 1, 2 ,4 degrees or whatever they have been mapped for.

This is a feature oringally on the ECU for in applications other than on the cossie as far as i know (dont forget these ecus get used in loads of places), rather than specically on the cossie, but its very useful potentially for either big doses of gas, or running different fuel types.

Thats probably true!

the wires to alter the ignition timing are for different octane fuels.
