Just set up an appointment for next Tuesday to have my Baseline dyno run. Its being done at Modacar in Livermore California. 3 runs for $75, then when i get the chip i go back and get another 3 runs for $75, so it will be $150 total. So hopefully we can get 6 other members to chip in $20.

Scott- let me know about the deposit. Do i have to send you my ECU to be reflashed, or is it software/chip that you send me?

 

Your ECU contains a chip that is soldered in the holder. You either have to mail it or go in somebody else's garage to have it done.

 

best news since speedmax...

 

THANKS CB... the SUN Inazma HYPERVOLTAGE will be something i will look into. what was the 1st noticeable difference? actually... maybe... if you can, start a thread on this topic... interesting...

nice idea regarding the sale of the results.... but i don't see them buying it...

 

Elow... your hyped-up 4 this... driven... quick... thanks!

BALDWIN has a point about the removal and installation... research this topic thoroughly with the shop that will do it...

this will obviously raise the project price.


look logistically, UPSOLUTE has 5 takers already... i say upsolute takes the 5 at the group price and one, preferably the 1st xf re-chipped... to get the dyno test... and if they do stand behind their product AS I WOULD!!! they can do the group price for 5... knowing that when there are positive results from the dyno ... upsolute will have a very large database of clients here in this forum...

but people, i have a gut feeling their are minute gains at best made with this chip...

they say strength comes in numbers and the truth always comes out...
upsolute... why does it seem that the forum has to beg for results???

 

I'll put in $20 for a dyno pull.

I had the Upsolute done in my red Crossfire, and I know something changed....it pinged like crazy in 110 Fahrenheit weather in Phoenix and 91 octane gas! (pinging stopped at about the 65 degree level) That is actually a good thing...it proves that the timing is changed and/or the air/fuel mixture was leaned a bit. I believed the car felt faster, but can't guarantee it.

A thing to also consider: My MPG went up by around 2 mpg, even with the summer-time pinging. This shows that the hp gain is more than just a peak event…it is an across the board gain. A quick calculation shows that this increase in MPG is worth about $2.50 per thankful of fuel...which works out to be a savings of about $70 per 10,000 miles of driving.

I do have to agree, though, that what I felt as being faster could easily have been a placebo effect. Even if a full 15 hp is realized, it would only amount to around 0.25 tenths in the 1/4 mile and 0.20 tenths in the 0 - 60 mph times, or thereabouts. This is not a *big* difference and the general rule of thumb (for cars in the 12 to 16 second 1/4 mile range, roughly) is that you need about a 0.3 tenths of a second to feel a difference.

For a reference to what 0.3 tenths would be like, you can achieve that difference by changing the air inlet temperature by around 70 degrees (1% hp change with every 10 deg F change), which is the difference you car would see from driving on a cool night in the spring vs. driving on a hot afternoon in the summer. Careful here, this difference is with the A/C off, so don't be fooled at first thought when you say, "Oh yeah, my car feels much faster in the winter than the summer!". I believe in general that most A/C units rob around 10 hp, so when you compare air conditioned summer driving to winter driving, the loss is probably close to 25 hp, which is almost twice the hp gain we are hoping the chip will provide.

For me, I felt the Upsolute chip was worth it (even though $400 can't really be called chump change). Even if it really wasn't that much faster, I did realize an MPG gain, and the possible placebo effect of the chip translated into an experience that felt real and I enjoyed every minute of it.

 

thanks for that good lump of info... because reading thru the threads... most of the "chip" holders here believe they have seen some gain...

so this helps me to jump the same band wagon...

 

Drop me an email and we'll finalize everything. You will need to mail me your ECU, I suggest sending it on a Monday if possible to ensure that the weekend doesn't delay the return shipping.

Will this dyno be done on Cali-91 octane? What type of dyno is it? Do they have proper cooling fans? I'd ask that you get AFR recorded, also note temp, air pressure and correction factor/method, gear used, ask for corrected and uncorrected data. Typically dynojet places will give you the data if you bring a disk or flash drive, the graph viewer can be downloaded from dynojet.com, this will allow easy analysis. Take revs to redline and not just HP peak. Note tire pressure.

 

Thank you for sharing your impressions.

In the g-meter data shown earlier by another member it looks like the 1/4 mile time was reduced by 0.4 secs or so.

*edit* this is the plot I am referring to:

To me pinging is a very very bad thing...

 

just shows you how fake that dyno is, measuring "crank" horsepower...

 

the plot is from this thread which I linked to earlier:
https://www.crossfireforum.org/forum...highlight=dyno

As long as the before/after was multiplied by the same % to approximate driveline loss there is nothing wrong with this plot. I don't know if he did a coast-down to compensate for aero drag. I'd like to see the raw data set. Driveline loss is usually about 17% on a RWD car, a bit more for an automatic.

The chipped car appears to have done the 1/4 mile in 14.6 or so vs. about 15 for stock, using quickie web calcs would mean about 15-20 hp or so to do this.

 

I should probably state more clearly my description of the pinging. I said it pinged like crazy...I would like to restate it to: It pinged to where I could clearly hear it in the 110 degree weather. I have been in cars (older 70's vehicles in high school) that pinged into detonation and were much worse than what I experienced in the chipped Crossfire.

That being said, it was a bit disturbing. What made it ok for me was that my mpg still was higher than w/o the chip, so it probably didn't matter too much. The increase surprised me, even to this day, because the knock sensor probably pulled back the timing as far as it could go and you would think at this point the engine would not return better mileage. I am going to conjecture that from what I have read, our Benz engine is a thin-wall cast block and transmits motor noise more than most, and therefore mild pinging that may not be heard in other engines is probably heard in ours.

 

What does pinging mean?

 

My PayPal Acount is: En023@yahoo.com for those of you who plan on donating to the Dyno Fund. Baseline run on Tuesday!!

 

send me your address... i will send you a money order.

thanks

Pinging means > bye bye to your motor. If you don't have enough fuel in the A/F mixture > your motor will detonate.
In simple terms > your pistons are turning into clam chowder...
Pinging sounds like marbles being shaken in a glass jar.

 

Hey guys, i'm still set for the dyno run tomorrow. I talked with Scott from Upsolute, and he has informed me that i will need to send him my chip, at that point they will re-flash it with the new data, and then send it back to me. He also wants the full $250 for deposit, plus additional $50 for overnight mail both ways, and i'm also looking at $150 for the dyno runs. That being said i have had no donations so far which is pretty disappointing considering that everyone has been dying for proof. I am still going to go ahead with my dyno run tomorrow, but i will not be sending my chip off with the deposit until i receive some donations towards this effort.

 

Well!? i just got your address today... wifey has been ill... i do not use my CC nor bank account #s on line... hence... no paypal... i will send you MONEY order...

thanks
josh
