I think the question I have about the chip is the expectation of an improved gas mileage and speed. City driving can only give me an average of 19 miles per gallon instead of the 21 that the stock had.

0-60 is an average of 8.0 using the stopwatch which may be unreliable due to the warming temp in Texas compared with the cooler temp last March.

I'll be shopping for the Escort G-Timer now especially that I'll be expecting my magnaflow muffler to arrive next week.

 

Cyril.... Something isn't right. Your 0 - 60 times are way off. Even if you had the traction control on you should be way quicker than that. I think my times with traction control on and just slaming the throttle is somewhere around 6.8 - 7 seconds. Your car should be running right with mine. I just gased up today (@ $2.04.9 per gal. 93 octane) my mileage on the last tank was 24.6 mpg.

 

That's what I suspect that maybe at that time Jason ( the Upsolute guy in Dallas ) had a hard time loading the file in my ECU, made some phonecalls to Rene then load a different file and not the one he had trouble with. I'm just guessing that's what happened and i cant really see whats in that file. A G-timer might answer the question if I had it or not regarding mileage and speed.

 

Hi WMichaels are all the Upsolute locations use the same file or is there a difference from location to location ???

 

Differences in the ECU number. As was explained to me today while I was having mine done...

There are different ECU numbers based on when the car was manufactured. As they manufacture new models, they may make adjustments to existing settings and will therefore change the ECU number to coincide with those changes.

Upsolute have programmed a few Crossfire chips and have programs already on file that may match your ECU number. If not, then yours needs to be read and a program developed.

Upsolute ECU Upgrade

 

pageoneresults is exactly correct. Your Upsolute rep will read and download the files from your stock chip. Then match it with the appropriate remap file, copy that file to the new chip and you're all set. They keep your old file so if you ever need/want to go back to stock they can do that with no problem.

Keep in mind too, that our ECUs and all engine functions are exactly the same as the 2003 SLK 320 and Upsolute has chipped a bunch of them. That's what they used for mine, since no other Crossfires had ever been done before.

 

My rep just spoke to Rene I'm almost certain this will get done to my car. + K&N filters. Thx for tip Wes. Will take your recommendation

 

By the way, what kind of fuel does Upsolute recommend? I've been putting 93 octane on mine eversince I got the car

 

They recommend 91 octane or higher. Same as stock. The primary reason we need to run 91 or higher octane is because of the 10.0:1 compression ratio. Lower octane fuel could predetonate (ping) and cause damage to the pistons and valves.

 

You're very welcome... You won't be disappointed.

 

Wes, I sent you an email on your Headlights. Again sorry to bother you with that, but I'd appreciate it if you had any info on the subject. Tried looking through here, but couldn't find definitive answer.

 

Got the email and sent an answer.... And it's no bother @ all. My pleasure, any time.
