Converted to E85

Your truck didnt have e85 at first and you just added injectors?

Yes and no.

Non-Flex Fuel truck, and all I've done is have a tune made for me by BBP to run a 50/50 mixture.

I'm thinking of getting larger injectors, but not sure if I'll see an improvement that will justify the $$$ for larger injectors.

So you didnt add the sensor?

LOL!

No, just a tune from BBP...that's the only thing I did.

You're going to have problems I think. I think the only reason your truck is running is because you're running some gas.  You need the sensor

That's the beauty of having a BBP tune with AutoCal. You can have tunes made for any mods you make to your truck.

I.e. if I add headers, I can get a tune for that and if later I decided I want to install a cam, I can get a tune for that.

I'm sure there are other handheld tuners that can be used, but I prefer BBP as they have great customer service and I think are more flexible with what they can do for me as far as tuning goes.

Well I have been running it like this for over a year with no issues, so I'm not convinced of the need of a sensor since the ECU has been tuned.

You're in CA, so you should give them a call and see what they can do for you...you probably won't have to wait as long since they're located in CA as well.

I had to wait until they did a tune here in TX, but once the initial was done, all other tunes are done via email....nice!

I wouldn't let bbp touch a pinto if I owned one.

They don't do Fords...to each his own I guess...but that's what I did and I have no problems and great acceleration/pull. Of course I also had them tune my tranny which helps with staying in the right gear longer.

Unless there’s been a change. The only difference between a flex-non flex fuel truck is the sensor, a hundred dollar option. Also unless there’s been a change, with the sensor you truck would tune up the truck by 25 HP. I think I would have went with the sensor.

Ok so I figured it out. You can run e85 mix without a sensor but only at the ratio of the tune. So let's say you need gas and the station doesn't have e85 to mix.  You're screwed and the vehicle will run like crap. Has to be the mixture the vehicle was tuned for and nothing else.  So it seems like a huge hassle to do it that way

I don’t understand your response. My GMC was E-85, ran well on all gas. The best on E-85. If I was going to run an engine tune I would run a E-85 tune. Running a tune for a mix of 93 gas mixed with E -85 would be a lesser tune for lower octane versus an E-85 tune. With the sensor you would get more hp out of E-85. You still could run other grades with self adjustment.

If your truck was not originally an e85 I'm saying

So how is the sensor different from a tune?

They both talk to the ECU to do operate the vehicle correctly without throwing a CEL.

I guess I should ask this question to BBP and see what they say.

Sorry to inform you, but your hypothetical analysis is incorrect.

My truck is tuned to run a 50/50 mix, and if I choose to, I can run 100% 93oct and not have any problems...I just can't run 100% E85.

I run 93 only during the cold winter months without a problem, so no biggie other than loss of performance if there's no E85 available.

This is factual and true data.
