Firstly, get all the tuning info you have stuck in your head for years and years and throw it out the window. This is an EFI motor and everything you think you know, is wrong. No longer do you need to worry about changing anything if you go from slip on pipes to a full blown shorty setup. People may tell you otherwise, but thats because EFI bikes havent been around as long as carburated bikes which do require a retune every time you change the air flow. For the folks who ride upside down (land down under), your 98 is close to our 93 when it comes to what fuel to run when using a PCV/Fusion and my map.
This includes altitude changes... How in the hell can that be? Well, the ECU has a sensor that measures the altitude and tell the injectors how to compensate. All the PCV/Fusion does is intercept this signal and applies the map thats loaded into it accordingly based on the AFR chosen for that given map cell point.
For the Honda VT1300 family (Fury, Sabre, Interstate and Stateline), there is only ONE solution for getting more power, better mpg, eliminating the 100mph limiter and overall driveability all at the cheapest price. That is the DynoJet Power Commander or the sister (as in twin, same unit different label) Dynatek Fusion, model #16-025. They are made side by side and only get a different sticker, although for some reason the Fusion seems to run cheaper.
Paired with my map, for under $1000 over a completely stock bike, you can get about a 22% increase in power, which is 12-15 whp/tq depending on the exact setup you have. This price is full pipes (not stock or slip-ons), a K&N drop in filter with a modded stock airbox and the PCV/Fusion. You also get 40-55 mpg along with this power, depending of course on how you ride. Under 60mph in 5th gear, even with 2 up, you can get 55+ mpg. Crank the throttle above 70% and youll get kicked in the pants hard. Seriously, you need to hold on tight till youre used to the difference. If you dont, youll die.
When i started doing the work and research to get this amount of performance, there were two other options, only one of which i previously deemed an "ok" recommendation, but after a few years, ive decided there is no comparison. Under no circumstances do i EVER recommend a Cobra fuel controller, mainly because they waste time, money and fuel because they CANNOT adjust the timing curve, which is where the power lies, at least on these bikes. You cannot make more power on this motor by adding fuel. The stock mixture is already at 12.1:1 and ive seen unburnt fuel coming out of pipes still as liquid.
My map is a combo of 14.1:1 AFR below 70% throttle and 13.5:1 above 70%. The stock mapping is a pig rich 12.1:1 for most of the curve and when you look at the fuel portion of the PCV map, you can see how much fuel it takes out. It also pretty much eliminates any decel pop from the pair valves.
The other choice is the ECU reflash from Guhl Motors. I no longer recommend this option for a couple reasons:
1. They continue to reap monetary benefits from a fellow VT1300 owner (who no longer owns nor is a part of the community), who spent money on the PCV and Autotune unit to build a map using no tuning knowledge whatsoever, simply tuning by the seat of his pants. This isnt a bad thing, but the map is numb and doesnt have the same power curve nor driveability and certainly not the MPG benefits.
2. After 5+ years of offering their service, the price hasnt changed to be cheaper. And they offer no support like DynoJet or I do.
3. Having the fan turn on at a lower temp is not really a feature, it doesnt make the bike run better or worse, having a better tune has more of an effect cause the air fuel ratio is better.
The PCV is plug and play, despite what some will tell you. There are 5 connections for which there are plugs (injectors, coils and crank sensor) and one connection that is a tap of the Throttle Position Sensor (TPS) wire (comes with a PosiTap for this). Install ranges from 45mins to 4 hours depending on the mechanical ability.
Once the map is loaded, youll need to do two things:
1. Calibrate the TPS. In the PCV/Fusion software and with the key on but not running, go to PC/Fusion Tools->Calibrate TPS. Click the < button to set the min value and then crank the throttle and hold and then click > to set the max. Then click OK to save. The values should be anywhere to under 1 volt for min and no more than 5 volts for max.
2. Enable RevXtend: PC/Fusion Tools->Configure and tick the RevXtend box.
