OpenFlash Tablet

[Shiv@Openflash]

In an open tuning environment (when people can make any change to any part of the ROM), there is an inherent risk with allowing for partial writes. This is not an issue when you are operating in a closed environment which, in a sense, can protect you from erasing/moving code necessary for communications. Until we can assure that there is no risk of a customer bricking their ECU, we will write the entire ROM. Yes, it takes a 3-4 minutes longer than doing a partial write. But it's a lot safer and will undoubtedly keep people (including some tuners) from disabling vehicles. These are all very big concerns for is given the scale of our customer base. We do encourage customers to custom tune themselves for with the help of experienced tuners. But along those lines, we also implement safety protocols to minimize (not to eliminate) risk of nonrecoverable hardware failure.

Good to hear insight from other tuners with OFT. Its a shame, because I've been asking about flex fuel, other F/I applications, and e85 starting issues, and haven't gotten 1 reply from either Shiv or through their support staff in emails... Seems like all they really care about is selling another tablet from what I take it.

Very discouraging.

Very discouraging.

I have said several times that we do not have any immediate plans for flexfuel. And supporting other FI kits will involve extended access to a local test car. In the past 3 months, we have added both Vortech and Phantom SC support to the OFT. As well as implemented enhanced datalogging (available today) and rest of world ROM support. While we do want to sell more OFTs I think it's fair to say we are doing so by giving what most of our customers want. We can't possibly meet every demand immediately. But I believe we are doing a pretty good job of adding support/features as time/resources permits at no additional cost to our pre-existing customers.

Again it is great to hear you have been working on datalogging as we have been asking for that for many months now. However, you still haven't answered my question. I attempted to call about it and a few other questions but never received a call back. Could you please tell me if there are plans to improve on this? This ends up costing a lot of money in dyno time for even basic tuning. Not to mention my personal time when doing more than 1-2 flashes for "quick" general fixes.

Are you a customer of ours?

Thank you for the straight up answer. Sorry if I riled you up I know you guys have plenty to deal with over there and are busy I'm sure. I'm just a little upset as well since my issue with the tune hasn't even been answered on here or in email to support. Can you at least answer me, are rough cold starts (on e85) in 60 degree ambient temparatures normal? Rough as in car literally won't start and stalls before it gets starting...

I mean this is just mild socal weather nothing crazy.

No worries. You are referring to cold start running E85 right?

Yes. I'm running the stage 2 EL e85 tune (all stock aside from that).

Cold start is going to be a function of temp and ethanol formation. If it's higher than 85%, it will definitely give you cold start difficulties regardless of ambient temp. One suggestion is to try running the revised cranking enrichment table values as prescribed by others who have solved similar problems. There really isn't much more for me to do on this end since we have not experienced those issues ourselves with our local E85 fuel source.

Thank you. I might get an ethanol tester to be sure of fuel quality.

I'll look into the cold enrichment if it continues to be a problem.

Maybe I misunderstood something previously or missed a post saying I needed to purchase hardware to support OFT as a tuner. I have had a number of people contact me requesting custom tuning using OFT, and FI tuning on OFT. This is why I have asked you about logging a number of times via PM, posts, and phone calls. Are you saying I need to purchase a tablet to ask a question about your platform in "open"? I don't see why your post was warranted vs just simply answering the question at hand that both me and @jamesm had. Both of us are attempting to support your platform but I cannot seem to get ahold of you or get any answers. Maybe there is a specific email I should be using instead? At this point you are making it more than difficult to attempt to support this platform and are making me lean more and more towards simply respond to people with something such as "If you want any custom tuning you will need to sell the OTS, or have shiv tune it for you".

Ecutek uses full writes and does so in around a minute on the right hardware, fwiw.

Does oft support any sort of auto recovery? Ie if my kid pulls the cable while I'm flashing, can it recover from this?

I wouldn't call it auto recovery, but I accidently did this when I got the tablet and I was able to be fully recovered in less than 20 minutes.... after I finished freaking out and worrying about having to get the car towed for a bricked ECU. I just had to reflash the stock map and I was good from there.

Yes, the OFT does have a recovery mode that should recover an incomplete right. But it's not something I recommend testing.
