Default hpt to bin

I'm trying to convert an hpt file to bin so I can adjust fueling in tiny tuner...it's getting harder to start on e85 now, I'm sure it might be an issue in the winter. I have an older version of hpt 2.24, could someone help me out with that?

Thanks!

Its been a while but I think you can just open up the .bin with HPT and drag and drop each field over. I don't think can can go the other way.

You just looking for a IFR table? I can dig up my old HPT files I think.

@TommyGloves would be good to ask.

I don't have a bin file, that's what tiny tuner is looking for. It couldn't read hpt unfortunately.

Here's what I'm trying to accomplish, supposedly takes care of cold starts on e85 -
Quote:

This is a subject of heavy debate even though the science says that E85 most certainly starts to have major evaporation issues below 32*F. Mostly because some people never have a single cold start issue. "Issue" being a car that takes more then 5 seconds of cranking to start. This could be due to differences ranging from altitude to how much compression your car is running. I know that I had zero issues with my L36 block SSM90 supercharged setup starting in my home town of Sioux Falls. When I moved to the higher altitude Rapid City area it was a bit harder to start but still very manageable all the way down to -30*F. Now with my new L67 setup my car took 30 - 45 seconds of cranking and throttling to get it running any day it went below 10*F. After doing the change I will outline below I now have instant cold starts regardless of outdoor temperature. Your results may vary.

1. Get a copy of your current tune in .bin format. This is because the table we need to access is not available in HPTuners. I am also fairly sure it isn't available in DHP. If you use DHP to tune getting a .bin file isn't an issue because that's what it saves anyways. If you use Hptuners you will have to email their support team a copy of your current tune and request that they convert it to a .bin file for you.
2. Download and set up Tiny Tuner. There are numerous guides on how to do this floating around.
3. Open up your .bin file in Tiny Tuner.
4. Go to Fuel < Base Fueling < Crank Fuel vs Coolant Temp.
5. Multiply the 10*C cell by 110%
6. Multiply the 5*C through -40*C cells by 120%.
7. Save the file and flash it to your car.

@m_dogg Glad to hear you didn't upgrade your HPT. They took out the BIN edit/save option with the newer HPT upgrade.

The easiest way is to get a bin version is to read your current PCM with a PT. There isn't a simple file conversion from HPT to BIN (that I'm aware of). Shoot me a text or PM. I think you still have my digits.

Will do.
I have the new version of HPT on my other laptop, I don't like it as much as the old version for some reason...

you can still downgrade your hpt, look over in gpforums for the dropbox link of all the softwares. the old hpt will let you save in bin i believe. i know it lets you open them for sure. i used to use that as a way to still use tiny tuner and still use hp to flash.

Before you go through all this, try a new tank of fuel. Flex fuel is transitioning from summer to winter vapor pressure. If you go to a slow moving station, you likely have a very low vapor pressure fuel. Low vapor pressure equals hard starts.

Vapor pressure is why the gasoline content varies. Some stations do a better job of keeping the vapor pressure high without having to lower the gsaoline content. I find that Speedway is much better than smaller brands.

Thanks for all the input, TG got the job done

The station I go to has quite a few e85 customers every time I'm there. It had the highest ethanol content from all other stations I water tested in the area - 80% winter, 85% summer blend.

You missed what I'm trying to say. Higher ethanol likely means lower vapor pressure which means harder starts.

Most stations need to go down to E70 to keep the vapor pressure up in the middle of winter. You should expect you hard starts to get better this weekend with the warmer weather.

Gotcha. I was forced to fill up at Shell the other night and had no problems starting in the morning. If I remember it right that station was about 65% ethanol last time I checked. Makes sense.

Also, you can go back and fourth with upgrading and then downgrading, then back up if you need to. every once in awhile if i need to change a vin or need tiny tuner for something. ill downgrade back to 2.x, upload a bin into a hex editor, change vin, save, upload to TT, make necessary changes, save, then upload the bin to HPT and flash. Then for the nicer scan functionality of 3.x ill re install the newest version of hpt. trust me you wont get froze out of being able to go back and fourth, ask anyone whos been using HPT for a long time, they know what im talking about.

I hope the author solved the issue, but I decided to share my experience. If you are looking for the way to convert hpt files, I recommend to check this site. It suggests software that can help to read/convert it. In general, this program knows all file types, not only hpt, so I'm sure, someone will find it useful!
