  1. V88 Laptop

    in ViPEC V Series

    Posted

    i have been using my HP Pavillion 17 inch screen laptop for logging/tuning. i want to switch to a smaller 14 or 13 inch screen machine so it will be easier to secure while i am on track at the Texas Mile.

    technology has marched on and i would like to take advantage of the faster machines.

    most of the newer Intel powered i7 machines run on a 64 bit architecture. will my V88 work with 64 bit?

    is there any advantage as far as logging speed with a faster machine?

    the newer machines offer a 3.0 USB. will the 3.0 work with the V88?

    any specific recommendations?

    thanks!

  2. EGT sensor selection

    Dave,

    i second Scott's suggestion re Exhaust Gas Technologies. they offer a wide range of EGT related products that i have used for a number of years. i especially like their line of new voltage conversion modules (amps). they sell into the true professional racing market and offer very competitive pricing. their line of themocouples is broad and i strongly suggest you contact them so that they can build you the exact setup you need.

    i have no affiliation w them other than being a satisfied customer. 

    excellent guidence from Scott.

  4. Xtreme coil compatibility

    in Link G4

    Posted

    Hello to all in Linkland, this is my first post.

    i am switching over from the Power FC to a Link Xtreme and am seeking some ignition advice.

    currently i employ two Jacobs FC3000 CD amps to power two MSD 8253 coils that spark two leading NGK 6725 plugs thru Magnecor 11mm wires. i run the two trailing plugs thru the factory setup using two MSD 8207 coils.

    i have no observable ignition problems at 8600/24 psi/500+ SAE hp w pump 93 octane and two Bosch EV14 injectors supplying 100% methanol. they are currently wired in parallel to the gasoline secondaries and run thru a FJO Peak and Hold module. lead plugs are run as wasted spark. (this will of course change w the Xtreme.)

    the primary reason for my post is that my 8253 coils have .16 Primary Resistance.

    a statement in the wiring document states:

    'One dual post coil (with a primary resistance between 0.4 and 1.0 ohms) is required per 2 cylinders.'

    i don't know if this resistance requirement is meant to apply to non dual post coils so my question is am i O K w my 8253 lead coils or do i need something different?

    i would appreciate any suggestions that would optimise my Xtreme setup.

    thanks,

    howard
