Dissapointment. TRM vs. Turner chip comparison.

[thedean]

$100 bucks. $50 bucks for the dyno, $50 bucks to get there and back...

[318isbmw]

James and I told you about trm's stuff.

^whatd you guys say about em brendan?

[318isbmw]

Never liked trm. James use to be very vocal but has quieted down in the last year or so. My experience was like yours, not terrible but not what was expected. Sorry I thought you had heard our rants on nwbmw

Hmmm thanks for the input. Never heard from James or you about them.

Update with dynos?

[JGood]

Coming from someone who has spent an hour on a dynapack with various 24v chips, back to back, with consistent oil temp and AIT, and spending several hours on the road with them as well, I can tell you that "butt dynos" are fairly inaccurate.

Get on a dyno.

I hate to dig up an old thread, but after having a very similar experience today I felt it appropriate to share my experience.

TRM Chip:

s50 manifold
s50 cams
540 HFM
24lb inj
LTW Flywheel
93 Octane
Rev Limiter: 7000

Turner (Conforti) Chip:
Euro HFM
LTW Flywheel
24 lb inj.
Speed sensor delete
Rev Limiter: 7000
Chip #: 5060-3005-SS (from their chip catalog)

Car is a Obd-1 95 M3, and both chips were tuned for the appropriate modifications.

I've been running the Conforti chip for years, but after seeing so many people on these forums loving their TRM tunes I thought I would give them a try. I installed the chip and gave the ECU time to adapt before I would turn the thing wide open.

Much like the experience OP had, the low end torque really wasn't there anymore with the TRM tune and it felt like the whole powerband shifted up 500rpm. I had to live up top to get the same pull i got at lower rpms with the Conforti tune. The conforti tune pulled with ease from 3k-7k while the TRM tune still struggled down low. I had to get the car to a little above 3.5k to get the car to pull.

After seeing so many people love TRM and their tunes, I was just disappointed that the car felt less powerful all around. I fully intend to dyno both chips to get confirmation either way as I am as interested to see the results as anyone. Will update once I get the numbers.

This is because it is not possible to make more power in the engine if engine is not pumping more air than before!
BMW made a good job on their ecus there is no 'hidden' power in the ecu program. They made the best overall generic program giving best power and best emissions.
If you consider the whole power curve torq and hp from BMW engine and compare it to the stock vs. TRM chart, you will average out with no power gain at all. You got to get more air into the engine to make more power.
What TRM did is advanced the whole ignition maps, made the vanos come one little early, you will notice more of a 'roar' coming from your air filter and you will 'think' engine is making more power,

Too bad you're wrong, gomer. Dyno charts will show it. But as usual, you talk shit about anyone you can and make it sound like you know everything. Hows the pirated chip buisness?

The stock tune is always conservative, because it has to pass emissions, and because the average driver will use 87 rather than premium.

funny how after all this time all this thread has are ass dynos. You realize after you've actually dynoed it, you can send the chart to trm and they will fine tune it from there?

Im not saying one is better than the other but this thread is still as pointless as it was when the origional ass dyno was posted years ago.

Dynos are important. The great irony is that more top end power will make the bottom end feel weaker.

Exactly what I was thinking. Like I said earlier in the thread, I spent a few weeks swapping chips, then hit a dyno with them all. It's amazing how much of a liar the butt dyno is.

I'd like to say with 12 years of daily driving e30's, autocrossing and tracking e30's, and driving everything from an automatic 325e to a v8 e30, my butt dyno would be fairly well calibrated by now when it comes to e30's. It's not. It always lies.

i would like to second the notion.

where are the dyno charts?!

needs more header and less bitching.....
