Very cool project you have Was it alot of work involved converting to awd?

Lury, This is info regarding the wires from the Can cable that I got from Ray: Brown = Gnd Yellow = Rx Grey = Tx I have not tried it... Hope it helps

Nice one:) I love the sound of the inline 5 Do you have some dynosheets of it?

Yes you can. I use it in my Evo 2. Here is cut and pasted from the help file: Example - Using Launch Control Mode #3 and Flat Shifting Together Both Flat Shifting and Launch Control Mode #3 require the use of a clutch switch to activate them. This has caused some confusion during configuration. The following example is intended to work through setting up both these functions to work in harmony. Note that settings given are examples only and may not be suitable for every application. Setting up the Digital Input A clutch switch must be installed at the appropriate position in the pedals travel. The switch should operate just before the clutch plate releases (or just after the clutch engages when the pedal is being released. The clutch switch must be wired to one of the ECU's Digital Inputs (Only Digital Inputs 1 to 8 can be used for flat shifting). Launch Control Mode #3 uses the digital input as Level Sensitive (recognises as being on or off) while Flat Shifting uses the Digital Input as Edge Triggered (recognises a change in state on the Digital Input pin). For the rest of this example it is assumed that the switch used is of the normally open type and has one terminal wired to 12V and the other wired to the ECU Digital Input number 2. This would give 12V on the Digital Input pin when the clutch is pressed and 0V when it is released. Under the Digital Inputs menu select DI 2. Set the Function to GP Input. Options will appear to set the On Level and Active Edge. Set the On Level to High as the input voltage goes high (12V) when the clutch is pressed. Check the operation of the clutch switch by selecting the Digital Runtime Display (press Ctrl + F5) and select the Digital Inputs Tab. The item labelled 'GP Switch DI #2' should read OFF when the clutch pedal is released and ON when pressed. Set the Active Edge to Rising. Rising edge is used as we want Flat Shifting to activate when the clutch is pressed (not released). The voltage on the Digital Input RISES from 0V to 12V when the clutch pedal is pressed. Configuring Launch Control Under the Motorsport menu, select Traction Control. The Launch/Traction control configuration page will be displayed. Set Traction Control to Launch Mode #3. The following options will appear: · Soft Limit - Set this to the desired Launch Control Soft Limit RPM (eg 5000 RPM). · Hard Limit Addition - Set the value that the Soft Limit value can be exceeded by before the Hard Limit is invoked (eg 100 RPM would give a Hard Limit at 5100 RPM). · DI ON/OFF Control - Set the Digital Input channel wired to the clutch switch. In this example channel 2 is used. · Ign Trim Activation - Set the throttle opening that must be exceeded before Launch Control will become active (eg 90% would mean the throttle must be nearly fully open before Launch Control will operate). · Arming Time - Set the time the clutch must be pressed for before Launch Control will become active (eg 2 seconds). · Launch Ignition Trim - Set the ignition advance to be added when Launch Control is active (eg -10 would give 10 degrees retard). Using the settings described above, Launch Control will become active after the clutch has been pressed for longer than 2 seconds AND when the throttle position is greater than 90%. Launch control will soft limit engine RPM at 5000 RPM and hard limit should the RPM exceed 5100 RPM. Ignition timing will be retarded by 10 degrees from its normal value while Launch Control is active. Configuring Flat Shifting Under the Motorsport menu, select Flat Shifting. The Flat Shifting configuration page will be displayed. Set Flat Shifting to ON. The following options will appear: · Cut Period - Set the time period that the ignition will be cut for during gear changes (eg 0.2 seconds). · Activation Point > - Set the minimum RPM at which Flat Shifting will operate (eg 4000 RPM). · Activation Point > - Set the minimum throttle opening before Flat Shifting will operate (eg 90%). · DI Control Channel - Set the Digital Input channel wired to the clutch switch. In this example channel 2 is used. Using the setting described above, Flat shifting will cut ignition when the clutch is pressed (not released) for 0.2 seconds if the engine RPM is above 4000 AND the throttle is open more than 90%. Due to the two second delay on launch control it will not become active during flat shifting gear changes (unless they take longer than two seconds !!!).

If it got worse, change the threshold values in the opposite direction, and only at that rpm you have problems.

Try with different filter level (1-4) and with different arming treshold values at the rpm you have problems with.

Very nice car and impressive 1/4 mile times as well :shock:

Hi Niven It may be caused by trigger errors. Open the triggers which is located at the bottom in the software screen. Check when the misfire appeares, if the trigger error counter counts up, then you are having trigger issues. Try to increase/decrease at the rpm you are having trouble with. You can also try with another filter level. If you are having trigger errors, I will post you my trigger settings on a STI with similar issues. I tried to open the file, but the battery in my laptop was dead, and I could not find the ac/dc adapter. Think I left it at the dyno... :oops: . Will try tomorrow

@Marcel B Try this cal for the early IAT sensor:

It may be caused by trigger errors. Open the triggers which is located at the bottom in the software screen. Check when the misfire appeares, if the trigger error counter counts up, then you are having trigger issues. Are you using reluctor sensor? If you do, try to increase/decrease at the rpm you are having trouble with. You can also try with another filter level. Also confirm that you have not switched the + and -.

Treads are 6 mm x 0.5 mm. 0.8 mm clearance. (1.6 revoulution counterclockwise after it have touched the compressor wheel) Ray, how to compencate for different # of blades? I have a 14 blade wheel. Which Calibration DI should I use? Thanks Ben Stian

I believe that your MSD require dwell edge "falling".

Nice project!

Hi Jason Connect to A24 Here is the wiring diagram: http://www.vi-pec.com/techdata/VipecKnockAmplifier.pdf

Hello Stian Yes you can remove it.

This car have according to the enginebuilder documentation a 3071R, 850cc injectors, EJ25 block, stock 2.0 l. heads and cams with the VVT removed and a FMIC. I installed the Vi-PEC plugin, a 7 bar mapsensor and a air tempsensor just before the throttle body. The car starts and runs beautiful. Power: Boost:

This is a customer car which I made a "Plug n Play" adapter to the original engine harness to keep engine wiring look stock. The car have a ported head, stock cams, 850 cc injectors, 3" stainless exhaust, RS500 IC and a modified T34 turbo. Car drives and idles like stock, but with extra power when needed The V44 controls idle solenoid as well. Power: Boost: Plug n Play adapter:

Try to change the trigger threshold voltage.

Bruno, try to lower the trigger 1 filtering to level 1 or maybe level 2. The trigger error counter should only increase at startup and stay at that value when engine runs.

Hi Jim A 4 cyl coil pack require a 2 channel igniter. 1 channel for each coil. You can use Bosch 0 227 100 200 igniter which your Vi-PEC dealer can supply you with. Wire like this: http://www.vi-pec.com/techdata/Bosch200_2coils4cyl.pdf

400 whp are nice in a rwd:) I have 7 bar mapsensors in stock. Now the V44 are available with 7 bar internal as an option:) Yes it will be on my Dynapack. I try to stay clear of screamer pipe, but it is ok as long as we can put a long pipe on it an connect to the exhaust extraction system

Looks good! What hp are you aiming for? Keep up the good work:)

You must be online with the ecu to see and setup knock table. The Vi-PEC help function explains how to setup and you can look at help without being online. Go to Help- Content and type "knock" in the search funtion. The Vi-PEC help are VERY good at explaining the most of the other functions as well I think 2-3 degrees should be an ok starting point if it sees any knock. Warning: Knock Control should be used as a safety feature only. It is not design as a tuning aid to help determine optimum ignition timing

You must use an external amplifier which outputs a 0-5 V signal for the V44 and plugin boards . You can use the one Ray sells or Phormula KS-4 for this.

@ rh (at) nissan200sx.dk Have sent a RB25DETT basemap to you.
