Hi is it possible too mod my old parma turbo controller ?

problem is that its too much ON/OFF when i drive its working q good for box 12 driving and g27 light but its a hell to start in glue and in some turns if am too hot the car can jump out when i pull full power

my idea was to change the resistor to a bigger one to day i hawe 1 or 1,5 ohm ...so is the handel softer with like a 3 or 4 ohm resistor ?
i whant it too be smoother when i start and softer when i pull full speed...the best would be some delay like 0,1 sek before the handel gives full power when i hit the gas...or is it time too give this old one some rest ...


found this on the net...

for the buck it seams good if it works...

This would be a good place to start.

They have a conversion kit to modify your Parma Turbo into an adjustable electronic controller.

I've built many conversions and full kits when I owned my raceway.

I would get a Parma 3 or 4 ohm Resistor and just replace it.
Even thou I have two Difalco's I use a parma 3 ohm with the FCR hard bodies and I use a parma 7 ohm for the Jail door cars.

and if you can do the Fleming hinge it is like silk.

If about 80.00 is not too much you may want to get a Difalco module. The DD229 should be just what you need.

Group 12 and hotter motors REQUIRE more WATTAGE from your controller than just a turbo resistor can provide. They are really only rated less that 30 watts. You can use 100 watts or more. Only the external resistor/bridge rectifier option exist or the complete change over to a transistor system such as the DiFalco/3rdEye/Ruddock style or others similar from Europe.

I would keep your controller (as is) for drag racing, or change the resistor to a 3 or 4 ohm for low end motors such as 16D or falcon/retro classes.
