OpenFlash Tuning Tech: Tales from the Dyno (Stock, Ecutek and OpenFlash tunes)

This is not even remotely true.

You are free to use as many tuners as you want. I personally have had tunes from 4 different ECUtek tuners on my car (Visconti and FA20 when NA, MotoEast and Delicious Tuning with the Innovate). Sure, if the original tuner chose to lock the tune file then a different tuner can't read or modify that rom, but they can certainly flash their own tunes.

im going to go with visconti based on what was said about the tuner in the first post lol..im going to leave it at that before thread gets out of hand.

they specifically stated that it was not visconti.

I've been wanting an off the shelf or mail order tune, and have been contemplating going with ecutek for awhile now....so glad I waited out. I'm sold on the OpenFlash but I'm curious to know if there are any variations to the factory ecu tune between the US and Australian delivered models? Does anyone know?

I don't know much about ecu tuning (hence the reason why I'm after an off the shelf tune), so if I did get the openflash 'Baseline Stg1' maps, should I still get a dyno run to verify stuff like AFR's are fine? Or can I trust that everything will be ok?

i missed that part then between helping ppl here at work and what not

I'm going to make a highly technical argument here that most people are not going to follow. It's an argument based on firsthand experience with Bosch, NGK/NTK, Denso (like the stock FT86 sensor), and actual emission benches.

You cannot fully trust any wideband to represent actual in-cylinder AFR when the engine is in a scavenging condition. It doesn't matter who made the wideband or where it was placed.

What that means is, AVCS cam phasing skews wideband readings to read lean, because extra "unused" air passes through the engine out the exhaust valve. If you are in a high overlap condition, where intake pressure exceeds exhaust, the wideband can read much leaner than what is in the cylinder. The only way to judge is to compare readings with an emissions bench, fuel flow meters, and air flow meters. They don't read nearly as quickly as a wideband sensor, but you have to do a sensor correlation to trust any readings.

There are a number of common methods of calculating air fuel ratio. One is to use a wideband O2 sensor with backpressure compensation. We don't know how the logged stock wideband reading is calculated, but if it's anything like what I've seen, there could easily be a backpressure compensation and a scavenging compensation applied to the reading. The other methods calculate based on the gases that come out of the exhaust. The most common are probably the Spindt method and the Fa gley-Nunez method. You can also infer scavenging and skewing of the wideband based on the CO% and O2% concentration.

Basically, on an engine with AVCS you can't make blanket statements about how lean somebody's tune is (in the actual cylinder) with only a wideband, either the stock one or dyno instrumentation. The scavenging skews the reading.

That's the point, that they can't see anything. You start from scratch out of necessity rather than possibly by choice.

I know its pieced together in the various post, but I thought I would put it together more directly.

With regards to the capabilities, there here is nothing wrong with ECUTEK nor OpenFlash.

There are some packaging differences. OpenFlash give you ability to see/share the actual ROM changes and use whatever software you want to edit files.

Your tune is as good as your tuner. Ecutek and OpenFlash are simply tools to write to the ECU.

If you give a monkey an ECUTEK or OpenFlash, it will still be a monkey's tune.

Exactly, but OpenFlash has the upper hand by allowing end-users to be in control rather controlled by monkey tuners claiming to be master tuners

Lol @Sportsguy83 My tuner seems to tell me all about my car, about the maps etc especially when I did know anything lol and has tuned a frs that has taken abuse my a driver who redlines on the daily and abuses it and also made great numbers with 16,500 miles and going strong as a DAILY ! so my " master tuner " is working great for me and I'm sure I speak for others as well

Guess we'll have to go back to old school plug reading

Lets end this right here. You cant post your biased response and then not have enough balls to just call my name. Thats just closet jesturing.

I appreciate your effort allow shiv to beta test on your vehicle but you should have done it impartially. Especially since you sent me one log where you car was running extremely rich. your LTFT were disabled so I could dial in your maf scaling and you never submitted any following logs as a follow up. My tunes have never been advertised as a “Canned” tune and never will. I tune every vehicle specific using you datalogs so if you never submit a log it will never show full potential. Your base files primary purpose to to have you log and a RaceRom enable rom which allows for some of the extended logging parameters to be recorded such as IAM MAF voltage etc.

Your email g=here stated yourtime line and concerns 1 week before your track evet yet you never opted to send back your logs



OpenFlash and ecutek nay sayers have built everything up into the fact you cant tune your own vehicle. Well the issues is neither can 95% of the brz/frs owners. Ive always been in favor of directly tuning each car and getting rid of the whole canned tune idea. This is why my tunes are always tuned remotely for free. If you dont take advantage of that then youre honestly throwing your money away when you make a purchase from my company. It takes allot of time and effort to get everyone up and running but its the best way to guarantee results.
From there you tune is built on and edited using your tunes. I welcome the fact you and Shiv would consider me a fake tuner seeing the success ive had and the openness I offer my customers to take their cars to the dyno anytime and have me tune for no extra charge remotely. I would not give anyone that option knowingly without the confidence that my final product will perform as expected. Here is your original log showing your LTFT and to why they were disabled to start your tune.



I understand the fact that I have asked questions regarding this platform over the recent months and jumped on board makes me seem like the major obstacle to overcome but i have always said I favor open platform just not tuning on them. Lets do some math for a bit. The offering here is still a retail/profit item call it open if you may but the software was created years ago and freely distributed. OpenFlash seems to have robbed either ecutek or brzedit of def files in a couple months and now are selling a handheld that is openly sold for about 175-225 depending on volume purchased for 500.00. even brzedit doesn’t allow the reading of ecutek roms but Shiv has managed to dump a file from a competitors product. And one thing i noticed is why was the base file you had Jeff’s IAM set to 1.0 when the only file I sent him had it set to factory .7. So at this point I dont understand why you edited the file and what else you did to try to lend credibility to your dyno session. I would always be willing to compare tunes but to the extent that you are trying to push your product and hack code from other vendors im yet to be a fan. im sure some other ecutek customer in the area with either e85 or forced induction would be willing to let you pull a map to create your next tune. im sure that will save you boat loads of time.

Then the validity to the product is mixed in with thats like going on the dyno and shiv loading one file and not being allowed to revised or make changes as he did so I don’t consider that a true comparison. You file is as incomplete as it can get. And why would you think that you would have to pay a local ecutek tuner to revise your tune, when I have always offered this remote tuning service for free of charge. I have verified this information from our emails and you submitted one log which I replied with an updated file to disable your trims so I could dial in your maf scaling and afr targets and you ceased communication at that point. I can only assume that you have some reason for doing so. I don’t want you to think you were slighted in anyway or form with your purchase because we have and always will offer remote tuning. And you can verify this because all my tunes will rarely match up to another other than base settings each other value is edited throughout the tuning process just like on the dyno.

told it like it is? they used an incomplete tune to do the comparision looks like.

i cant see the pic you posted on a gov computer
