Do you have the software and a laptop to connect to the Go-tech?

If there are no tuners there you're going to have to learn to DIY. Once you're connected to the Go-tech you would need to enter values on the various screens in the zones of the map as some one cranks the car. More than likely those are blank at this point.

Save the existing map before you start and keep it safe. Then make incremental backups as you go.

It might ultimately be easier to chuck the Go-tech for a system that is in the area or surrounds, but good tuners are rare to begin with.

As a matter of interest, which Go-Tech system is it?

My advice, don't use your project car as a daily.

Get a Citi Chico or something to run around with while you play with the project car.

Funds are abit tight right now i have to use this as my daily. If I adjust the cold enrichment when motor is at 5 degrees? Or pick up the timing to 16 deg on the 0 to 500 rpm range

It's like I got to choke the engine for air when starting of I press down on the gas it will never take. So what I do is I swing her without pressing the accelerator like 5 times then after it starts to get some kinda life I give her some gas slowly and it starts

Its going to be a very careful balancing act in all the screens. Coupled with the mods done to that motor it would be difficult to advise what needs to be changed in the map. Might need to chat to the tuner who installed the Go-tech, send him screenshots of the existing Map and run the changes past them.

As I said, make the changes incrementally and save a copy of the map after each change as it improves.

Just make sure you've made a backup of the existing map as it is now and keep it somewhere safe.

I used to struggle with my modified Citi at cold start as well. On a different management system though, and despite all the fiddling that was done, the cold start was never right, it got "better" but I was always cranking for 2-5 minutes in the mornings.

Driving and cruising was great, car made decent power. But trying to get going on a cold winters morning was a certifiable nightmare some days, and this was on a bone stock 2L 8V.

My neighbors called it the Popcorn machine because it would occasionally backfire from the cranking :lol:

Cold start setup is a real struggle even on my Fuel injected Uno running spitronics Titan ECU. When its cold in the winter season, its a struggle to get it started and once it has started i keep the revs slightly up with a Shifting spanner that i place on the accelerator which i keep in the car.

Car runs, drives great with awesome fuel consumption. I have learned to live with it until i can get the car retuned again with MRD tuning or Juan at JETuning.

Watch this video to understand how it works technically and what is needed, Yes Gotech might not be the same, but the theory will help your thinking when tuning it https://www.youtube.com/watch?v=jTL1OlmY3kU&t=2s
