Dr Datsun here, I been doing alot of learning about turbo powered cars and am going to install a meth/alcohol system on this turbo tom car as the previous owner has given me a brand new SMC controller but had no installation instructions for it. So I am reaching out to the performance people who might have an installation guide or wiring diagram for this unit. The wastegate overhaul should be done this week so I am ready to put this bad boy on the road. After that it is going to the dyno for tuning so the controller needs to be operational. Any help here is greatly appreciated. best wishes to all 510ers Dr Datsun.
