OFT Review (Vishnu Tuning Tablet first impressions)

[RyanOver9000]

I've been researching this since the beginning and finally took the plunge and ordered mine today. I'm extremely excited about receiving this. My only concern is I've heard some complaints around the compatibility of my current setup with the OTS tunes.

I've got the PERRIN CAI 2.5" and Inlet Hose and run on 93 oct. Can someone confirm that I shouldn't have any problems? I may have jumped the gun on ordering this, but it was such a great looking product and is the most affordable thing on the market. I couldn't pass it up.

I'm in same boat. From what I understand, the 2.5" Perrin intake has the same MAF voltages as stock from 4500 on up to be safer, with a bit of difference on the low end. With a tune not expecting the low-end difference, smoothness of our DD will probably be affected.

It is supposedly relatively easy to to correct for this though. I wish someone with the know-how would write up a nice DIY.

I think it's strange there's no official word on this especially given how OFT sells the Perrin products on their store. It seems like they are marketing them to go hand in hand, but there is no official support tuning wise.

I have the perrin cai with the oft stage 2 and posted a log not too long ago, being told my car is running rich and the probable cause was the perrin cai.....

I have a question tho....looking through the software the other day to change the 2 step rpm activation point, I noticed that from what I could see, fuel and ignition maps as well as all other maps were tuned up to 7400rpm, yet the rev limiter is set to 7600rpm.....can someone explain to me how this works? Is that extra 200rpm just not tuned? Or is there something happening I'm not seeing

If the last RPM breakpoint in a table is 7400, it will retain that mapped value above that engine speed. So no, it's not untuned above that

Also, I don't remember seeing a customer log with the Perrin CIA. So if you would repost it or take another one when you have a moment, I'd love to see it.

Cheers,
shiv

Currently running the stg2 E85 EL tune on stock headers (waiting for my OFH to arrive to go UEL E85 stg2). Is there enough of a noticeable difference between the 1.42 and 1.56b maps to make it worth switching and going through the re-learning?

[Jolaessss]

Curious..I'm currently running the RevWorks UEL, stock over/front pipes, and Invidia N1 CBE. I still have the O2 spacer in one of the header ports from when i ran without a tune.

now that i currently have State 2 UEL installed, would anyone recommend to remove the O2 spacer? thanks!

@Vishnu; do you have the possibility to create 95oct or 98oct maps for European customers?

Hi! These RON definitions suppose to match with US AKI 91 and 93 octane somehow. Don't worry, it works perfect with Euro 5 98RON fuel.
This one is just flashed Stage 2 unlearned WOT pull log

And this one is log of good learned ECU Stage 1 same 98RON octane

^this is exactly why I haven't purchased the OFT. I'm running the 2.5" Perrin CAI too and am not going back to the ugly stock intake box after spending hundreds of dollars on an aftermarket intake.

I have read that running the Perrin CAI can cause the engine to run rich, which is bad for the engine on the long run. I have also read that noobs should not attempt to tune/correct the discrepancies theirselves because it can lead to bigger problems, ultimately destroying the engine on the long run. It worries me to purchase a product that can lead to big problems on my new car

For us noobs, to spend another $200 for an e-tune on top of purchasing OFT just to run safely with the Perrin CAI isn't fair. Can SHIV or someone please help us guys use the OFT safely with 2.5" Perrin CAI?

I have done a lot research on the OFT and would really like to purchase one but this issue is what is holding me back on pulling the trigger on ordering one.

[Navadv]

^ what he said. Would be good to see if Shiv could help us out. Would make me a buyer of the OFT

Common shiv, help us out please.

I'm sure there are tons of people who would love a map designed and tuned around the perrin 2.5" intake, but what about all the other people who were mislead into buying various other intakes that need tuning to run properly? Should Shiv spend his time making custom maps for every single intake out there, especially after its been shown that intakes make barely any power, if at all, after a tune over just a drop in filter and modded snorkel?

What is not fair is the unreasonable expectations people have for someone who is selling a product and offering FREE off the shelf maps based on a certain set of modifications and then complain that he doesn't offer FREE maps for your mods. That is exactly what the etuning service is for. I'm sure you don't work for free and its unfair to expect Shiv to do so.

Does perrin provide the MAF scaling for the 2.5"?

Only the 3". The 2.5", just like almost all other intakes, are sold with the thought that it should be safe to run in stock form. Unfortunately, as I'm sure you are aware, they almost all make power just by leaning out the engine.

Ideally, there would be some how to post about how to scale your MAF correctly since buying a tuning solution gives you the ability to make these changes. I'm sure that is something that would be incredibly useful to tons of people on these forums (including myself).
