Has anyone dynoed a 128i with the evolve tune?

[wolfe]

I've looked over several of the threads here and I see dynos of AA tunes, evolve tunes of non-US spec cars like the 125i.

Maybe I missed it, but I couldn't find any for the US market 128i with the Evolve 3-stage manifold tune.

Can anyone help me out?

thanks.

I don't think there are any yet. We're waiting on a few members to have some free time to get some dyno's for us.

Any 125i dyno of Evolve represents the limit for us ( if you have the 3stage manifold).
We share same DME/ECU. The difference is fuel and exhaust ( are 125i secondary-catted?).

Therefore, the result is the post facelift 130i power levels, maybe slightly more.

Are you sure about the ECU? I thought ours were different. You'd think that all N52-equipped 1ers & 3ers would share an ECU, but I recall seeing something about different ECU's in an AA thread or somewhere...

Both the 130i LCI and 128i use the MSV80 with the same part number. Which is also why Evolve is able to tune the 128i as they have them effectively on hand in England via the 130i.

Also, I think all MSV80 cars tune to be 80% the same.
With the differences being in the middle of the powerband - ie how you solve the dip and how much Torque is extracted. The top of the rpm range is usually very simmilar, with the differences attributed to fuel Octane.

Source: an unhealthy research habit fueled by passion prior to tune which included an excel sheet and a gallery of dynos

Its the MSV70 cars that show very different numbers at the hands of a German tuner ( a us spec 325i with a eurobox and NO 3stage was tuned by DS, result is highest Tq ever seen on the dynojet for a n52 when it was dyno'd stateside. the HP was inline with msv80 328i stock ~230hp crank).

The decision on tuner I think comes down to planning to do something about the headers some day and the emissions issues.

EDIT:
There are dynos of 125i with Evolve in Australia on an independent dyno, results in kW - claimed to be 20% gain at wheels.

Give me till May and I'll post up some results. Intake will be here in a couple days and the tune will follow shortly. Still saving up the dough for that!

Hmm....

Absolutely!

[wolfe]

Great, thanks guys. Can't wait to see some dynos of the 128i.

Figure it this way, My AA tuned n52 puts down 218rwhp with DISA and 225rwhp with catless headers and DISA. Evolve should easily be able to achieve that and more based off of their track records.

Its probably easier for someone to assume they are almost the same ( outside fuel octane and the area around the middle dip). The premium of evolve is a path for headers because of the o2 sensor tweaks to satisfy emissions plug in tests.

You are getting very good numbers, putting you close to 290 hp depending on the losses of drivetrain.

[631twentyeighteye]

I use 18% as recommended by the dyno shop, which puts me at right around 265hp. I'm happy with that. The car is a joy to drive and other than the constant o2 sensor issue's i've been having it's been great.

I would disagree, AA's tuning expertise has always seemed to focus on E36 era and before cars.

Alright

here is the Australian Evlve car
http://www.1addicts.com/forums/showthread.php?t=923769

Result is 152kW or about 203 whp. Assuming this is similar to SAE than this is good result.

Here is mentions of Autralian 130i's on simmilar dynos putting down 150kw

This I don't get. I mean, it may be true, but then again, it may not. Why hold Active to the standard of dyno-proven data but assume Evolve's results are any better...just because?

Anecdotal evidence aside, we haven't seen a dyno of an Evolve-tuned 128i with just the DISA manifold and stock headers to make a fair comparison to the Active dynos we do have access to. Facts is facts, and unfortunately we don't have a whole lot of empirical data when it comes to N52 tuning.

[631twentyeighteye]

Based off of evolve 125i dyno video's/graphs and the secondary o2 tuning of Evolve is my reasoning. I like my AA and can't complain about it besides not being able to pass plug in obd2 testing.

I guess that's a good starting point for conjecture, but I'm not convinced that it's an apples-to-apples comparison. I thought the 125i differed from the 128i from the exhaust manifold back?

[631twentyeighteye]

I'm not even positive myself, But i figure it's a close enough starting point. I don't think anything passed the headers will drastically change the RWHP numbers on the n52. Once stig or somebody else with evolve gets some pulls on a dyno we'll find out for sure. I'm hoping the evolve pulls some good numbers over AA so i don't sound like an idiot

I've seen first hand the improvement of their tuning when I I watched them remote dyno tune an E39 M5, E46 M3, and E60 M5, all of which were tuned to begin with. And this was on an independent dyno across the Atlantic Ocean from them.

Here they are picking up 50hp at the wheels over someone else's tune.

[wolfe]

No question they know what they're doing. I would just like to see a couple of dynos on US-spec, UL/low output 128i cars before I'm convinced to spend the cash.

The 125i and 130i tunes are good reference points but I want to see what kind of gains I'd be getting on exactly the car I have, running on the fuel available to me etc.
