If a flash failed using OFT ie car battery low or for some reason you unplugged cable or something silly causing flash to fail.

could you just write over failed/partial flash it or is it likely to cause more dramatic issue ?? assuming you were using OFT trying to write over a non locked tune ie an OFT/rom Raider/Tactrix/ecuflash created tune.

All you would have to do in such a situation is restore OFT connection (or recharge battery) and write to the ECU again. Nothing dramatic since there is software license involved with OFT.

So their is no chance of trashing boot loaders or anything, your only writing to the flash ram section of the ECU.

You can theoretically brick your ECU by writing a corrupt file (i.e., by editing areas of the ROM that contacts boot data, not mapping data.) It takes work to do that however.

Being .bin files you would be surprised. My computer opens them natively in notepad and I could really mess things up if I screwed around. You would be surprised how long it takes to open one file though that way.

sounds like it would be worth removing the file association ".bin" from notepad

Thanks.

good to know someone tried it with good experience. Thanks.

Thanks. I will try both and data log.

Shiv,
I think u have a great product and plan on buying one soon. Just wanted to know if you offer a map for 93 octane. I've read u dont have a map 93 octane , but that doesnt seem to make sense to me. Can u help me out here?

[stevo585]

Same here as most of the country is has 93 available. At the least maybe a suggestion on a few things that could be tweaked?

[StormTrooper]

Cali has the worst gas in the lower 48...acn(Arizona California Nevada)

As far as I know you could add in a little more timing but from what I've read it won't make a huge difference without a good tuner and a dyno to notice where you can add. (could be wrong)


Any chance of releasing a version two EL header tune for JDL and nameless? I don't mind paying for the e-tune but I can't really get cam settings dailed in that way.

Any "tuning" done without a dynamometer is a shot in the dark. All we can do right now is tune for anti-knock and AFR with the logging capabilities we currently have.

On a side note, I've noticed some buggyness with the latest OFT update. With the OFT plugged in at start up I've gotten warning lights in the dash come on several times. Namely the ABS the traction control and today the airbag light. It goes away upon shutting off the car then restarting. This never happened before the update. Anyone else get this?

All our gasoline (non-E85) maps are intended for 91-93oct. 91oct users may see their Advance Multiplier float a bit from time to time. But 93-94oct users will see it stay put. 93-94oct guys really have it lucky. Then again us 91oct folks get to enjoy sunny CA while the rest of you get snow

With the OFT plugged in, all it is doing is drawing a tiny bit of power from the 12v supply in the OBD2 socket. It doesn't even do any active communications unless you request by going to datalogging or writing or getting info. So I don't see how plugging it in can cause any of the dash lights you are reporting. This has not been my experience at all and is the first time I'm even hearing about it.

I will take a photo or video next time I get this again.
