The sun is shining, wife has gone out with the mother in law, what could be better.....? Well continuing with my installation of course
Microswitch fitted and wired in, the BMW throttle box set up is made for a microswitch set up, theres even a radius'd ridge on the back of the pedal to activate the switch. Set the rpm to zero and activated the switch, pulsoids buzzin away a good'un. Set the RPM to 2000 min and nothing so that part of the max is working great.Great news! In fact, I just asked about the trigger in your previous thread.
What min RPM setting would you recommendIt really depends on the car and what overall setup. In this case, I'd go right off idle in 1st gear with 50 bhp with the displacement and gearing of the Z4, especially if you're start power is less than 100%: the key is allowing the engine to freely accelerate. I whacked the juice on my 1.4 liter in first gear with 25 jets and 100% start power with good results.
Ive definately broken the back of it now (i hope), I'm going to order myself a pressure transducer before i get the bottle filled, i've already installed the cabling for it and will probably fit a bottle heater at some stage too.
I know I've still got some work to do but whilst I get to that I have been playing with the power settings to get a feel for it, what baseline settings would you recommend I start with, eg power, build time and delay time for the 1st gear and then for the other 5 gears.Keep it simple and start with 25 jets. Starting in this way allows for finding any hidden gremlins, allow you to adapt to using the system, and if you do happen to make a mistake, then the chances of damage occurring is minimal.
Keep start power at 100% throughout all gears and power points; build time can be set to the max; 0 delay, unless you have traction issues.
Am i correct that the delay time setting for the 1st gear is to slightly delay the delivery of the nitrous to prevent an overly lean mixture and what sort of figure should I start with, bearing in mind the engine in question? ThanksThat delay is for the overall activation of the system: it allows for vehicles with traction issues or weak drive train components to get rolling before adding more power. You need to go into the 'System' menu to access the nitrous/fuel delays. You can set it to the minimum to 100 milliseconds nitrous delay for 25 jets and for short pipe lengths. If you have long pipe lengths, then more delay may be needed once the power is stepped up.
Overall, the settings all depend on what you feel the car needs and how it responds. You have the ability to decide what you want it to do with the Max Extreme, you pretty much have god-like power at this point. You just have to learn to how to use your power
