SMART Tuning question

Hi guys I have a question for those people ho tuned the SMART system, so if my SMART Timing template is lets say -2 does that mean that I have to put in that particular load in my Timing template -2 of Timing ?

No, you may only need -.75 or -1. Have you found your noise floor on the SMART timing table yet? If you don't, you'll be retarding a ton of timing (-2) using the stock template map. I am assuming you have the GT35R on the car.

I just did some logs with CommsLog and no sign of knock but my SMART Timing is puling Timing constantly, and yes I have a RNR GT35R on my car any input is appreciated thanks.

The first thing you should do is lower the boost as much as you can and put in some race gas (You can use pump gas, but do lots of runs and error on the conservative side). Zero out your timing map and do a map trace of the SMART timing table. Hit print screen button so you can save the trace. Then zero out anything below that map trace line on the SMART timing table.

Here is a conservative one I did for my GT3076. My current one goes to 38 on the Y axis.

You need to do a good 3rd gear pull. Just make sure that your fueling is an acceptable range (low 11's high 10's after 4500rpm). If you see any values above 40 in the SMART timing stop the run and check your 3D maps for any weird values. Its nice to have somebody in the car w/ you doing the logging or driving.

Are you using SMART fuel also or are you using another wideband?

Your SMART Fuel map is going to have to be modified also (it's going to be crazy rich from the 3000-4500rpm range), but if you can get a clean run up to redline then you can work that out after the SMART timing.

Then you are good to go for some map tracing on the SMART timing map. Once you get a good baseline SMART timing map, then you can move on to removing fuel from the Fuel map and modifying the SMART fuel map.

When I did the basic tune on my car, I never used Commslog. All the data you need is on the map traces of the XEDE maps. Once you have a decent base map, then I used PyXEDE or Commslog to fine tune it over a long stretch of time.

Don't forget, print screen and paint are your friends.

Hey jj 008 look at this SMART map do you have any suggestion what should I do to eliminate the Timing being pulled (-2) in the upper load?
