Because your MAP calibration is different. You don't need to pull a vacuum on the sensor in order to calibrate it....it should be calibrated for atmospheric pressure. You probably need to seek professional help (the kind you pay for) if you want to resolve this.

So you are using some sort of CAN receive template for this? How can that be, as the Vipec has no user adjustable CAN receive parameters? Pretty nice setup, I have a couple of customers who would be interested in 08-10 STi support.

So the only devices that a V series ECU can receive from is a Motec E888 expander? I don't understand why there aren't some other common devices, such as Motec CDL dash or SDC/MDC diff computers. For example, 2007 Subaru STi has no speed sensor in the gearbox. I need to send the wheelspeed CAN data from a diff computer to the ECU. I suppose I could use my ADL dash to emulate the way that an E888 sends data out but that is crazy to have to do!

Is there any way to receive CAN data from a Motec device that is not an E888? Nothing else is listed when I try to set up a receive. Is there a way to create a custom CAN receive template?

Based on my info from Denso and on a search at Sparkplugs.com the Denso IK22 is a resistor sparkplug.

Hi all- This is a V44 in a Nissan 240 w/ KA24 turbo. No matter what I try, the ECU will kick offline as soon as the engine comes up on boost. The ECU will disconnect from the laptop and not reconnect until the USB cable is removed and reinserted and the USB drivers reload. Same symptom on multiple laptops. We are using an MSD DIS-4 Plus to fire 2 wire Denso coils from a Honda CBR motorcycle. We have used a similar ignition system on other cars with no issues. Spark plugs are Denso IK22, no misfiring at all, just ECU disconnect. I have already tried basic things like shielding the comms cable (also a choke), separating physically the ECU and CDI, and examining for loose grounds or bad connections. ECU firmware is the latest as well as VTP software. Any and all help would be appreciated. Thanks!

Thanks all. Figured out that the factory intake cam sensor is wired backwards in the stock harness (we made an adapter).

Is there a position sensor on the line lock? Maybe split the relay output or trigger to a digital input? You could use the first pulse of the VSS to unlock it. If your VSS only has like 5 pulses/rev it may not unlock soon enough. Maybe an ABS sensor will give better resolution.

Hi all, wiring a V44 into a 2001 USDM Honda S2000 with F20C engine. The crank trigger is 12 evenly spaced teeth, the cam has 3 teeth, 90* apart. If I select S2000 trigger mode, no PRM is shown even though Trig 1 and Trig 2 turn green in runtime values while cranking. I suspect this S2000 trigger mode is for the newer engines with different crank and cam triggers (similar to K20). If I use multitooth trigger setting I get RPM but the ECU will sync on the first cam tooth that comes around which is not working but maybe once in every 4-5 cranks. I guess what I am asking is how do we set up a multi tooth sync wheel without grinding teeth off the cam wheel? Latest firmware in the ECU, everything else works a treat. Any input appreciated.
