PC and Baz. controlling all 8 injectors?

Guy's I need some information. Can the power commander control all 8 injectors like the Bazzaz say's it can? PC says it has adjustments for "all injectors" but you can buy a separate controller to "control all 8" lol

I just need someone to explain what PC and Bazzaz can do for all 8 injectors pro's and con's, what one can do and the other cannot.

Any info or links to information would be great.


Thanks

Some of the PCs only come with 4 connectors for the lower injectors I believe. Then you have to buy a harness to be able to connect to the other 4 injectors. I believe most Bazzaz units come with connectors for all injectors. I believe the Bazzaz costs less.

Don't lick the hand that wipes.

The PC only Controls the lower 4 injectors out of the box. You have to add the secondary fuel control module to connect and tune the upper ones.

I may not be perfect, but at least I don't ride a Suzuki.

Ok thanks for confirming guys.

Anyone know if a common tune benefits from being able to control all 8 or would that depend on the tuner?

I've done extensive race tuning on upper injectors for at least half a dozen bikes in the last 10 years. Gains from upper injector tuning were rare and always happened at topend. No mid-range gains were ever registered.

Even before the PCV offered the SFM to tune the upper injectors we used to just add a second PCIII USB to get the job done and I have only seen verifiable gains on 2 of those bikes. The 04-05 1000RR on pump gas was the most notable it gained about 5 peak hp by tuning the upper injectors to deliver more fuel at high rpms and reducing fuel form the lower injectors in the same range. It was a time consuming effort and not worth the time I put into the project. As a tidbit of interest along the same lines I managed to get the same gains using an HRC ECU where I altered the injector bias to accomplish the same task

The other bike was an S1000RR race bike with the SFM running oxygenated fuel which gained about 2-3hp which is in my book completely negligible when you are talking about a 200hp engine.

The other bikes gained nothing or at least nothing I could consistently prove was attributed to the upper injector tuning specifically.

This kind of info I was hoping someone would share, thank you!

My next step is to contact my tuner and ask for their opinion for my setup.

A friend of mine asked me this very question and I can usually give a good answer lol but for a question like this I couldn't and that's why I come here ha.

PC5 is easier to use from a tuner perspective. end result on pc5 vs baz = the same tune to you aka, your ass won't feel much of a difference

Which ever you go with I'd contact the guys at riders discount. I went to my tuner and asked how much a tune was he gave me the price and I told him I'd be back after I got my bazaaz in. He informed me that his shop sold them and installed them for free if bought through them. I told him I was sorry but I don't think he could beat the price I was quoted by riders discount. So he asked and I told him. He replied he couldn't even buy them at that price. But since he told me he would price match he offered me a bazaaz at the same price then installed it for $30 bucks. I figured $30 was worth me not spending any time messing with it. But my main point is riders discount is probably the best price you will find.

For me I don't have a preference. Thus why I'll call the tuner I'm going to use and see what he prefers (which I'm pretty sure is PC). Got the info I needed on what controls what and if it's needed lol this site is great.

I've been in contact with Mike at riders discount before and I had planned on getting back with him for when I purchase. He's given me great prices before.
