87 and low octane gas

[alf]

Hi,


I am looking for an option for 87 or low octane fuels ECU map. I currently use OFT to upload maps.


The reason is not to save on money, but be able to travel long miles in places where only low octane / grade fuels are available.


Thanks in advance,
Andy

Buy some BOOSTane, 16oz bottle of premium would take 15 gallons of 87 to 94. Cost about $16 a can.

91 octane is available nationwide. Don't worry about it.

Even if it's cheap 91 octane it's still better than trying to run 87 octane.

Like said, that shouldn't be a worry here in the US of A.

Even if you are waaaay out in the boonies, they will have a "hi-test" pump. Now, waaaaay out there, if that hi-test pump is all rusted and there are spider webs on the handle, and a mud dobber nest in the nozzle, you may wish NOT to use that pump (hard telling how long THAT gas has been in that tank).

I would just pump a few gallons of regular to get you on down the road to the next station.

Lots of back country in WA, OR, ID and CA.
There have been a few crossroad hamlets with only a tank on legs behind the post office.
Usually have to go find the person with the key or only open from 6am to 9am for the farmers.
Some motorcycles with small tanks would have a problem.

The twins mileage has let me avoid them with only a small bit of advance planning
by filling up in a town with more than one station. They've got premium.

Howdy,


thx for the octane booster suggestions.




This is is for the trip in countries where there is no high octane fuel available. I probably need to do like 4k (s)miles in such places. It is not to save a few $sss..

PS. I am not going to Mars. But it is quite remote destination,

[Mr.ac]

Countries? Or counties?

Pretty sure Canada and Mexico have 91 octane too.

From personal experience I did the Baja 1000 road trip to Cabo then boat over to Mazatlán, to Durango then back up to El Paso, and back to California.

There was only two times where I had to fill up with 87 octane in the whole trip. Rest of the time it had 93 and 91.

Pretty sure our Canadian buddies/travelers can chime in too.

Just where do you plan to go? Pretty sure you can get answers from members in between your trip.

now it sounds like op is trying to save money and the traveling to other countries is just a ruse

You don't need a tune. The ECU will pull timing to protect the engine. However, since the engine was actually built for premium, your mileage and performance will suffer. A tune can't fix that.

if this is a case and engine is protected by ECU against low octane fuels, that's awesome.

I truly mean what I wrote. Cannot reveal details. Not yet.

It's protected on the stock tune, but don't expect to be making any power.

If at altitude and on 87 and your IAM value in the ecu drops to near 0 you're gonna be putting a bit of an extra load on your motor and it's going to take quite a hp drop.
