Got my bottle last week and dropped it in the mounts, and fitted my pressure gauge...

After faffing about coming up with an idea for a throttle body spacer to drop the crossfire injector in, i kept coming across clearance problems, and eventually i decided it wasn't worth the bother, as there was no real benifit anyway, so it got fitted to the intake pipe prior to the throttle body...

The MSD TPS/RPM switch i'm using gave me some issues at first...
I used the 0-5v TPS signal direct from the sensor, and the RPM signal that feeds from the ECU to the clocks.
First issue was with the system disabled, at about +50% throttle my car kept dropping into limp mode, with a 'EPC' light to follow... turned out the box was back feeding something even when powered off, to get around this i simply dropped a Diode into the TPS signal line with flow bias into the MSD Switch.. Problem Solved.
Next issue was that when i triggered the system (WOT & 3krpm+) it was pulsing it's output, and after some testing i realised it was the RPM signal causing this. I used an oscilloscope to monitor the signal which was nothing like the Square Wave i expected, the pulse was so short that the MSD box must of been missing them, so i had to switch to using a Ignition Coil Trigger... Problem Soved!
I also had a wierd experence with my static test, Redline is 7000rpm, so i set my RPM approx 2300 and energised the system, it smoothly reved to a smidge over 6000rpm paused for a moment and then continued to rev over 7000.
So i tried again with my start rpm at 2000, and on energising the system it hit just over 5000, paused briefly and continued to rev.... I decided this was lambda control taking over and leaning off the slightly rich mixture.
As it happens my car comes fitted with Wideband Pre-Cat Lambda Sensors as Standard (1.5v at 14.7:1), so i fired up the laptop and did a short run, whilst watching A/F's, and i was satisfied all was well.
Heres one of the logs i did, keep in mind 1.5v is 14.7:1 & 1v is Approx 13:1, you can see it go momenterally richer than usual as the system is energised, and then the ECU leans the mixture off very quickly.

I realise this is nothing but an average fitted system, but i'm very impressed with it... Only down side is i've got through 2x 5lb bottles in 3 days running 50bhp jets :-\ was fun though!
