Joe.... you know you can log fuel pressure on your MoTeC.... just add a sensor and you have full visibility on FP and can understand the effect of duty cycle versus pressure versus voltage drop at high load.....

Nicely done. Great to see rewarding results on all your efforts. Martin @ Precision Sports Inc.

IGN4 is the external ignition driver used to control the inductive coils. Make sure your overboost cut is not what is causing your issue: ADJUST -- FUNCTIONS -- BOOST CONTROL -- SETUP -- OVERBOOST CUT. It should be set at least 50kpa above the maximum boost you inted to run to avoid fuel cut on...

The dwell needs to be optimized for running higher boost on the oem ignition system with the MoTeC and IGN4 setup. Gap @ 0.018" and increase dwell 0,5ms in the dwell table for drag racing and the engine will be happy to 34psi+ boost. This should not be done on a trail application as the coils...

Here is a different twist for those not affraid to think out of the box: front mounted turbo with double wall water jacketed exhaust for proper underhood heat management. MoTeC ECU, no head shim..... 180kpa boost on 91 octane with closed loop lambda and closed loop individual cylinder knock...

Here is a video that shows the MoTeC M400 ECU in a marine application: 100% waterproof -- Motec M400 Marine ECU All MoTeC snowmobile products are available through Precision Sports

Mauri, Your idle timing is really up to you, anywhere from 8*btdc to 18*btdc. The right way to build a timing curve to hold a steady& clean idle is to build a compensation table that will get the engine to stay at a preset & desired idle speed. For example, if your desired idle speed is...

Good to see you're having fun Mauri! I'll get your head spinning here: start to imagine what ignition compensations you can build with RPM rate of change (ROC) at different load points..... then hold on to the bars on acceleration.... ;-) Trick we used on the MoTeC turbo Doo that recently won...

No, not at this time. The plan is to update the current M400 kit during spring & summer 2012 to include MY2011 & MY2012 models and fully support the newer IAC, knock sensor, power steering and Exup systems.

Here you go: Bosch EV-14, all units in Usec.

Let me provide a few answers as I am the person who originally conducted the developement project with MoTeC in 2010 and I have used and tuned MoTeC systems for many years. About the lambda sensors: the M400 will accept any 0-5v input from controllers such as AEM, Innovate or NTK. You can use...

Folks looking for higher flow injectors as 100% compatible drop in units should consider Yamaha OEM injectors that come on the Yamaha 1,800cc supercharged FZR jetski. External dimensions are the exact same as the Apex, connector is the same Denso style and low voltage dead time from 8vdc to...

Exactly, best method is to use a pulse modulated solenoid and a 3D map using rpm and TP as the X and Y axis. Using TP as an axis allows to anticipate driver power requirement and control the BOV faster for even greater throttle response.

The challenge at getting better fuel economy on a SC setup is much more closely related to perfecting the boost map than the fuel map -- the two obviously go hand in hand. Most SC setups put out too much boost at part throttle and the increased air charge pressure must be compensated with...

That's a massive amount of power on NOS. Key to going in that range requires setting up with proper timing compensation, otherwise things go BANG real fast. Not really different than forced induction -- proper ignition timing is key to success.
