Hey E9XPost,

Long time, not talk. I have decided to finally pick up a Vishnu Rev2.5 SE or a Rev3.0 (havnet chosen, id appreciate some input) finally. Ive owned the car for a year as of September 12th, and ive loved it, even at stock performance. My main question is:

What should i do to pre-pare for its first tune (that i know of, its used)? Specs:

-2007 E92 335i N54 6MT
-Roughly 37k miles. I bought the car a year ago with 33.4k miles and have put on about 3.6k miles. I have not changed the oil yet (i was going to wait until 5-7k, possibly).

The car and engine have been feeling a little "off" and boring as of the last month or two, so i thought that some extra boost would bring back the passion

My thoughts for getting a tune are two-fold:
1) Increase performance and fun
2) Use it to diagnose if my engine is running fine, which im not sure if it is, im a worry wart with it



Thanks for the input, glad to be back on E9XPost after a 3-month hiatus!

Eric

Change your plugs, get your intake valves walnut blasted. Other than that I would say you are good to go, just change your coil one at a time if they fail.

How much would each of those cost? I heard walnut blasting is pretty damn expensive. If so, id prefer to skip that until its really needed...

Would someone with a moderate know-how be able to change the plugs? Ive always heard its like Legos?

Change plugs and tune, dont worry about the intake valves until you get idle problems

Where should i buy plugs? How hard is it to replace?

Yeah, changing plugs is super simple. I've never done it before but Cobb has a pretty good video on their website.

As for deciding between the Rev2.5 and 3, if money isn't a factor get the 3 for the simple reason that it has native USB connectivity. Otherwise, you can run all the latest maps on the 2.5, it just requires fiddling with a serial to USB adaptor when you want to connect to your laptop.

Secondly, if you have a manual transmission, you can integrate the NLS feature with a few extra wires on a Rev3. Not possible with 2.5

Lastly, if you plan on running meth and the Vishnu E85 sensor at the same time, you want a Rev3 as it has multiple external channel inputs. With the 2.5, it's either/or.

Hope that helps.

Thanks for the feedback! Ill have to hunt around for plugs, unless someone would suggest what to get.

As far as 2.5 vs 3.0 goes, i have no intentions of going with meth now or in the future for a multitude of reasons. I plan on maxing myself out with FMIC/DPS/Cat-back/DCI. The NLS, is it worth having? I dont drag race (like once a year maybe) and simply wanted a nice boost in power for getting into trouble

Money definitely is a factor though, and id much rather buy 2.5 if i could get away with it. When you say 2.5 isnt USB-native, does that mean i wont be able to connect to my laptop with it?

Thanks for the info!

I haven't done plugs myself as I am only at 19k miles, but it's very easy, and COBB has a detailed video on Youtube on how to do it. You need a torque wrench, a socket tool (I reccomend the BMS one) and socket set.

Basically cowl off, engine cover off, remove coils, swap plugs, button up. Also, have you given the JB4 a thought? Outstanding tune that has E85 autotuning.

Thanks, ill have to check to see if i have those tools.

Yeah i thought of the JB4, but i really wasnt sure what to go with I was leaning towards Vishnu simply because of the extensive work with the single-turbo kit and Vishnus apparent knowledge. Would a JB4 better suit my situation? Honestly just looking for a Stage 1+, possibly Stage 2 tune that will make me giddy like the day i got her

Also, info i didnt tell you all:

I will be running 93 Octane ONLY. No E85, simply because i dont want to experiment with it

I am biased towards BMS simply because I have a JB4 and have not had any issues. It was a breeze to install and the features are well thought out.

That said, Procede is a fantastic tune as well. Both the JB4 and Procede are piggyback tunes, where the COBB is a flash tune. To be honest, COBB sounds like the best option for you considering you install it via the OBD2 port from in the car, and you can change maps based on the mods you have.

Id prefer to stay away from COBB simply because of that, I wont be changing mods very often, just once every couple months. Is the datalogging on the JB4 just as useful as the Procede? Does the JB4 offer the same wastegate rattle fix that the Procede does?

No problem The NLS feature allows you to hold boost between shifts. However this is only really an issue if you have upgraded turbos because our little twins spool very quickly as it is.

You will be able to connect to your laptop with the 2.5, you just need to buy a serial to USB adaptor. I would go for something like this, but I know Vishnu has a specific cable they recommend.

Hey thanks for the reply!

After reading everything above, would you recommend the Rev2.5 or the JB4? What im looking for is a strong tune for a stock car, useful datalogging, and features/customizable. I really am not sure of the major differences between the Rev2.5 and the JB4. If they are basically a draw, i will probably go for the JB4 simply because its a newer piece of hardware, and i could re-sell it for more down the road?

COBB has the best re-sale value if that is something that is important to you. I have tried the Proceed and I now have COBB and I love it. Its exactly what I want, clean, and I couldn't be happier with it. One neat feature with the Proceed and JB4 is the ability to change maps while your at a light, you can do it using the steering wheel controls but even still your car needs a few WOT pulls to really adapt to the maps you are switching to. The COBB you have to pull over and it takes a minute or two to switch and again need to do a few WOT pulls to adapt to the new map.

Changing spark plugs is super easy and this is the cheapest place I have ever found to buy them...

Um, oh dear..
As far as I'm aware, I don't think the JB4 is a newer piece of hardware. In fact, the Rev2.5SE is functionally more capable. For example, the latest version of the JB4 can only retard ignition timing via CPS offsetting whereas the PROcede can both advance and retard timing,depending on octane concentration and a variety of other factors.

As far as resale goes, I think they'll be similar. The 2.5SE is not vin locked so it can go from car to car without an unlock fee.

I run a PROcede and am biased towards it not because I own one, but because careful research led me to the conclusion that it is the most capable tuning solution for the N54. Thats why i bought it. Don't take my word for it, search for comparative reviews and speak to independent retailers who sell all of the major tunes. Jeff@topgearsolutions is probably one of the most knowledgeable and helpful vendors on here.

Thanks for the info. Sounds like the Rev2.5 SE manages the engine more completely. What kinds of features does the Rev2.5 SE have that would be useful?

[drewmeyer87]

I can attest to the fact that Procede is a solid chip. Not bashing JB4 at all, my buddy has one and his car runs pretty great as well. It's all subjective, but at the end of the day, the Procede pulls ahead.

Some people love the JB4 logging, I think it's a hot mess personally. Coming from a color blind guy... trust me, it's hell.

There is no difference between 2.5 and 2.5SE aside from the cool looking case (that you will never see) and the fact that it is not VIN Locked to allow for better re-sale.

I'm very surprised this thread hasn't turned into a tune war...
Good going guys!

so proud

I agree, changing the plugs is super easy. Watch Cobb's video on it. It will take less than an hour.
