Hi. I recently purchased a 2016 4rt standard model. My question is what do I need to purchase to modify ignition and fuel mapping? The trail I ride is an 80km loop with elevation running from 3000 to 8500 feet. My previous bike (Gasgas txtpro 300) required careful jetting to handle the changes in elevation. I expect the PGM-FI to be better but still would like to have the ability to make changes.

You'll need the HRC software. The setting tool (someone made one on thumpertalk http://www.thumpertalk.com/topic/1071987-10-pgm-fi-hrc-tuner-tool/).http://www.montesa4rt.nl/ has maps for above 1000m and 1500m if you want a starting point.

 

Some models came without programmable throttle bodies but I don't know which ones. If you post the number on the side of the tb then someone might be able to tell you. It will be something like xxxxx-NN4-xxx.

If the code ends in 315 its programmable I believe, the standard non programmables have the letters ed on them.

 

Thanks that helps a bunch. Hard to find much information here in Canada.

The 2016 models are equiped with a high pressure fuel pump, so you can't use the older map (2005-2015).

Mitani are working on this point for 2016 users.
