Are you using the controller for extra control? Does the ecu not have enough functionality?

no s40 does not control nitrous .the progressive controller i use (cold fusion) allows me to adjust the amount of nitrous on startline and build time

Cheers Danny, I had been reading this

But I see you can't build delay in.
I was hoping using a full throttle switch and then altering the RPM section to ramp it in as I got going.
I just don't want the full hit off the line.
Problem being I don't know what my launch rpm will be yet.

I know they are a bit antiquated but wet nitrous kits are pretty fool proof and their controllers are very clever and designed for the application. Nothing against EFI modules controlling additional fuelling - as they are designed to do - but matching that to nitrous flow is tricky and get it wrong even slightly and a lean condition melts things real quick!. I'd stick with a standalone nitrous controller - DTA for fuel and ignition, Nitrous progressive for gas injection = horses for courses.

yeah thats my thinking basically if the basic controller will take care of start % and ramp time .and ecu will switch it on at wot and at a set rpm then thats all you should need for a good nitrous setup .i use a bosch 044 for both motor and nitrous wet kit

Are you using a line lock and two step limiter? If so (subject to what nitrous controller you are using) it should be easy enough to dial in a start percentage and time ramp to 100% flow all activated from either clutch or line lock switch? With the bikes we used to launch WOT but 2 step limitted at about 5500 which was the just below the bite point on the auto clutch - system armed in pre-stage, one button for limiter and NOS activation, then keep hitting the shifter!

I'm using the s40 2 step on the clutch pedal and same microswitch triggers nitrous when released .its all good but i have a lot of tyre and the chassis hooks up really well so its a case of getting the bite point /2 step and clutch management to work in harmony .i ran 9.95 sunday with 60 foot of wheel spin so theres plenty left in it yet.... :twisted:

Is launch control an option? You just need an undriven wheel speed sensor.
