OK. Trying to do my first MHD flash. I pushed the start button three times quickly in succession but the system still turns off after about five seconds. How do I know when it is in diagnostic mode?

I set up my Google pay with Paypal and a credit card. Both failed.

Got my first tune and now my payment is being rejected to buy the MHD flasher. Does anyone have a definitive answer for this? Can I just buy Google Play Credit, which I've never done before, and buy stuff from MHD using that? No wonder people hate Android. Any further word on ios?

Good to know. I've already paid for two Twisted tunes because I want e85.

Thanks. This wasn't necessary in my previous car. Minor issue.

I did the Track Attack too.

Before I switch music source from iPhone to Sirius I have to turn the volume knob down by 50% to avoid blasting my ears. Am I missing some adjustment?

A number of years ago Car and Driver ran a story about engine break in. GM conducted a study using three Corvettes. One was driven following the typical "delicate" procedure apparently favored by most people here. The second was driven with no particular break in technique. The third was driven...

A tune is one thing. A bigger turbo is a different story. Presumably the OP is not concerned with powertrain warranty. A block on the OBD port is certainly a good idea. I had some sort of issue years ago with my 2013 Boss 302. Technician noted in paperwork "car has aftermarket tune. Not...

I received the wifi adapter but no tunes. The suspense is killing me.

I will be receiving my tune monday. If I use my Android tablet to install will I have to stay with Android permanently or can I switch over to my iphone once it becomes available?

In California it is illegal to replace a properly functioning cat, even with another functioning one. On the other hand new cars don't need a smog inspection for, I think, six years. I'm against going catless. I like to breathe (my '66 GTO not withstanding). I'm guessing a catless DP is probably...

I placed my order with Twisted Tuning for stock everything and 91. I also bought a second tune and plan to run e85 as my primary map. Once I go through the datalogging process on 91 and it is dialed in will I have to datalog again to run e85?

It would be good to know how efficiently it actually filters. I see HKS is still making their "mushroom" filter. I don't know if they have improved the filter media but I remember years ago when they introduced it. Probably the worst job of actual filtration of any filter ever made with the...

I was thinking of the convenience factor in a daily driver of just filling the tank with e85 without having to worry about ratios of e85 to normal e10 to achieve the desired ethanol percentage. I ran flex fuel in a GT350 for four years. e50 seemed to be the sweet spot as far as driveability...

On my Shelby converting to flex fuel was simply a tune flash but the Supra would require additional hardware, correct?

As far as e85 and lubrication, what about regularly adding Lucas Fuel Treatment instead of intermittent tanks of 91?

When do you expect the iphone version to be available? I do have an Android tablet but I'd rather not carry that around in the car.

So if you get an MHD with an e85 tune, which is what I want, does it also come with a 91 (California) octane tune to be able to run the occasional tank of e10?

I paid $5100 below msrp at Maita Toyota in Sacramento, CA this week. They have 4 more including a Launch Addition with a big markup. My car had been on their lot for 129 days, so long that there is a dash warning to replace the battery.
