It is cheap and easy to do . Go to **** Smith and bye a 3amp 5kohm potentio,meter. This is ajustable from 0 ohm to 5000 ohm. Hook it up to the ecu engine temp sensor located beside the temp sender for the temp gage. I think of memory I have mine set at about 2100 ohm withch sets timing at about 17 degrese cheak the resistance of that sensor for the ecu when cold and set your meter to that resistance but you have to keap it accesable so you can retard timing to start when hot. Sorry it has bean a while thanks to all of the info to-date from every one. Hope this info is of use to sume one.
