Ok, what is the difference between the EVOtech tune and the Inmotion tune? Evo is $1600 vs Inmotion's $500 "custom" tune. Theres a big difference in cost so this is why I ask......

 

I've been curious about that too. Also throw in Speed Innovations to that list ( how much does that one go for?). Is there one thats far superior or are they all about the same?

 

Exchange Rate?

"Evotech is a german based tuning company that offers custom tuning for any modifications that you have done to your vehicle!"

InMotion is based in Oregon..

I'll just add that a proper tune does make a difference and will provide HP gains.

I think it is important to know is what your current A/F ratio is.

 

Makes sense for price, but is anybody willing to step into the flames and endorse one as better than the rest?

 

Brian,
That sounds logical. Correct me if I am wrong, but I remember reading Chitown's thread "how to build a fast crossfire" and after he installed the NW intake and 178mm pulley he then got the ECU tuned by Inmotion. I believe there wasn't a huge difference in ET and MPH after the tune. So i was just wondering what the deal was with these tunes.

 

I was told that all of the software available for these cars is the same - so, basically, the 'box' tunes from all of the providers is the same thing (according to my source).

Anything 'custom' is extremly difficult and you'll pay for it.

I forget who told me this but it was not a private message and was on this forum, so it should be able to be located via search.

I also do not know if it is true - but it makes sense because most of the providers of these tunes due not have the ability to alter them or make them 'custom'. They just load and go.

Based on what I have read so far I would say that the tunes are bases on imperical data taken from tunes done on other vehicles with 'like' mods. These may be based on actual dyno tunes originally(we hope). They still sound like a good trade off to get peak performance from your upgrades without going to a shop with a dyno. My .02 worth.

I believe this to be true

The only thing Jessie @ SI was tweaking when he tuned my SRT was fuel maps and A/F ratio after watching the ECU adjust from Dyno run to Dyno run. I guess you could call it a "semi" custom tune.

A true custom dyno tune - is with a laptop in the car and watching the parameters live and tweaking them at various RPM levels as the car spins. Thus the fuel maps and other parameters would differ from car to car and tune to tune.

 

Not sure about Chi-Town tune results, but Chi did a Dyno run before he sent his ECU to InMotion and his A/F ratio from the factory was around 12.5 which is very good.

My A/F ratio from the factory was 10.5 - way to rich, even with the pulley installed - this was robbing me of HP so for me the ECU tune was a good thing.

Plus it raises your RPM limiter, SC engauge, and Speed limiter so you can hit 190 mph on the Texas mile........

 

Good points! I forgot about the RPM limiter and Speed Limiter.

 

All factory forced induction cars are faster after modifying the ECU mapping. They're all tuned at the factory to minimize warranty claims, so just leaning out the A/F a bit gets you 20 whp. That's not going to be mind-blowing max performance difference, but the midrange improvement is typically noticeable.

Just my 2 cents but it's really tough to justify any ECU re-map costing more than $1k. If the tuner really has experience with the car, even a custom tune is nothing more than 15 minutes on the dyno followed by another 40 minutes ridding shotgun while working the laptop. If the tuner doesn't have the experience with the car and its ECO paramters, it's all a trial and error exercise and you're basically paying to school him in what works and what doesn't work. By comparison, $800-900 on my Evo gets a piggy-back ECU set-up that enables you to switch between a few different maps (e.g., one for factory tune, one for 19 lbs boost on 91 octane, one for 21 lbs boost on 93/94 octane).

You have to be stupid rich....................or just stupid to pay $1600+ to just get the ECU reflashed for these cars. If you really want to have your mind blown away just look at how much Renntech is charging suckers to reprogram the ECU on the 65 series AMG cars(or any car they flash for that matter).

 

I love my tune by InMotion, 12.87 to 12.4 with custom tune. I believe my car is the fastest without a pulley posted on dragtimes. And faster than some listed that have a pulley.

 

Yes I think so ... The water/meth kit is doing wonders - with a 181 pulley I bet you get in the 11's

 

The 12.4 was with NO water/meth. But it should help out great when I buy a pulley. I would love to see 11's, but who would'nt

 

You cut almost a full 1/2 second off the 1/4 mile with just a Cold Air and Tune? I guess I'll gettting a tune then...

 

Bikecop,

I think that track elevation of 680ft may have something to do with your time. Probably pretty cool and low humidity. Boy I'd love to run there. Nice times. 1.80 60' with stock tires? Wow!

does the InMotion tune, advance timing? Just curious, because with a little shot of the juice 11's would not be a problem.

 

Anyone have an LET Stage 1 tune here? I can't find anyone that had it done. Also, what kind of gains did you get? Most of the people on this forum have InMotion or Evo so.......

 

I gained in my opinion a nice seat of pants difference and had a nearly 4mph in trap speed (plus a tenth in the 1/4). Thats HUGE! I'm hitting the drag tommorrow weather permitting so maybe I can beat my old best.

The difference between the two by the way is the same difference between renntech and ASP...NOTHING! It's kinda like buying a pair of shoes....if you get the Nike logo on the side you pay triple even though the walmart attack force can do the job just as well
