Ecu Disconnect when engine start (can't reconnect)

[Guest |427|]

Hi

Car spec

Engine 4g63 with 2-tooth crank trigger and stock CAS as cam-trigger

VAG cop running in direct spark mode

Primary injectors wired to INJ1 and INJ3 - 4x 510cc with ballast resistors INJ1 to cyl 1/2 and INJ3 to cyl 3/4

Sec injectors wired to INJ2 and INJ4 - 4x 1680cc with ballast resistors

Staged injection

Vi-PEC ecu running latest firmware

Computers used (same problem)

Sony Vaio running WinXP Home

IBM Thinkpad T41 running WinXP Pro

I can connect to Vi-PEC when igntion = on , engine running = no

I got the settings ok so the cars starts and can idle after ~5sec

But after like 2sec of the engine running the Vi-PEC ecu disconnects from the computer and I can't reconnect to it after that. Same problem on both computers and tried restarting them.

Download the current software from the website. This is version 4.5.1 Build 601. This version has new USB drivers version 5.4.30.

If you still have a problem, then the engine has non resistor spark plugs. Change these for resistor type. You can get very cold race plugs with resistor, so there is no need to use non resistor type.

problem solved , it was the sparkplugs

Thanks Ray

To bad i can't run the NGK B8EGV any longer (worked great with my old Megasuirt)

There is no BR8EGV
