Hello everyone.
I finally receivd the parcel from Quick chip today. My experience with them is not very good. First, they didn't gave me the instruction to install. The instruction they gave me was for V8 and V12 models, and the instruction doesn't provide much clear illustrations.
It is my first time touching a car's computer and I don't really want to take any chances. I have to call them long distance to find out the instructions, but is okay.
I finally got the chip installed, but I didn't get in to work until the second time. I have to re-installed it because I place the chip in to the slot in the opposite way. I think it is understand able right ? They didn't tell me which side the chip was suppose to be facing.
I got it to work, but the idle is bad. Everytime the car is at a full stop position the RPM will drops down to about 500 and it will start to raddle, and the car will acclerate itself ( actually moving if I have it on D) until the RMP it reaches about 1000. This raddle cycle would not stop until the car is actually moving.
I don't know why, maybe the computer needs a couple of days to reconize the new chip ?
Another thing is that the air coming out from the exhaust stinks.
I mean before the exhaust was pretty clear. but now it smells funny.
I don't know, Scott promises that there will be no side effects, but.. I really don't know until I get a hold of him.
I wasn't able to feel much differents ( 20 extra torque and 20 extra Hp ), the car is running a bit smoother, and responded quicker then before, but I can't feel 249 torque at 4500 ? If there is that much of a torque increase, I should able to feel something right ?
I was planning on getting a dyno test, but I have to take care the idle problem first.
Any one had input in this.

Pete regards

What model & year car did the chip go into? Any odd smell could mean too rich of fuel mixture.

Another thing you might want to check is have the car emissions tested. If it flunks you need to have a serious conversation with Quickchips...

Lee

Sounds like the engine is running too rich!! If you can have the emissions checked comming from the exhaust you will know for sure. Was there any idle problems before? It's common for this model to have build-up on throttle plate. The idle is controlled by seperate computer.

Hi, I call quick chip and Scott saids that the chip wasn't right. He also suggests that to put the factory chip back in.
Yeah, my car has idle problem before, but it seems to be minor. Actually the idling will occur sometimes when the car is not in motion. After I put the factory chip back in the car runs a lot smoother, and the RPM will remain normal.
Is that little idling cost by the build throttle plat ?
Thank you.
Message for Lee.
I will have a talk with Scott probably tomorrow, and I will inquire about the C36 chip.
I really want quick chip and super chip to set up a side by side comparison. Like have them send in a chip, and run them through dyno, on the track and on the road.
I mean is a pretty good way of advertisment, if their products are able to deliver performance as advertised.
I heard that a 500E can run high 12 in 1/4 mile, and 0-60 as low as 4.9 sec and that is with ASR. I mean is that possible ?
If the results are accurate, then it is faster then E55, Supra, Cobra, NSX, M5, Porsche 911.
Pete regards

Peter,
Glad to hear QC is standing by their product. An independent dyno is a very good test. It would also be great to get a G-Tech or a real dragstrip to before/after testing with the chip(s) vs stock. How much power you make is important, but how much quicker that makes the car is another useful barometer.

As for 500E's in the high 12's...possible but probably only on a modified car. This would mean 92 model year, 245+ width rear tires, cold ambient temp/engine temp, minor to mediocre breathing mods, ASR snoozed, etc. Of course, a 6.0 tuner motor could get you there no problem. The quickest I've done in a 500E was 5.3 seconds 0-60 with a 13.6@107.5 mph 1/4 mile time so it might be possible. That run was not repeatable as I've found your times drop off sharply the more consecutive runs you make in a 500E. Before I say conclusively that one car is faster than another I prefer to see them run back-to-back under identical conditions. On those cars, conditions can make such a huge difference that it is not entirely fair to say they are "faster" than xxxxx all of the time. For comparison's sake I've also timed the same 500E doing 6.4 0-60 with a 14.7@96.6 1/4 mile time. Your "average" run was about 14.0-14.3 with a trap speed around 100mph and a 0-60 in the high 5's. Had the 500E at a "slow" dragstrip (track conditions were poor so everyone's times were slow) and went up against a C5 vette. The 500E was faster until the engine temp got over 100 C, then the times were almost identical with a slight edge in trap speed to the 500E.

Always good to hear from you...Lee

Lee,

Actually, it CAN be done. My friend's 500E(1992)ran a 0-100km/h time of 5.1, and converted into 0-60mile, I would say his ran at time of 4.9 - 5.0 sec.

Also, his car(outside temp at 18C) ran a 1/4 mile in 12.7 - 13.4 sec. so, guess it CAN be done. 500E rocks....

One, one thing I would like to mention, is that his can has the same problem(advantage!!??)as my 400SE. His car can also run about 300 rpm beyond redline before the tranny up-shifts....

Happy Motoring...

akry,
Wow....very impressive. Was your friend's car bone stock? If not, what had he done?

As far as the redline issue...mine always hit about 6400rpm in 1st gear, 6000rpm in all others. It did however charge right past the supposed speed limiter at 155mph. Pegged speedo past 160mph till it redlined in top gear.

Lee

Thought I'd ring in on the 500E part of this string...mine'll do 6400 in 1st, maybe a tad less in 2nd, and 6200 in 3rd. No idea as yet what it'll do in 4th, but I have every reason to think it'll keep up with Lee's car as my car performed comparably at the strip under seemingly like conditions (14.1 in the 1/4 on a near 100 degree, humid day). Haven't hit the limiter yet, but plan to as soon as I heat cycle my new Michelin Pilots next week. Now, as I understand it redline=165 with the stock gearing, but with slightly taller gearing the car will do 175 before aerodynamics stop the fun. I'm real interested to see if the governor's indeed in place.

As regards the 0-60 times, I'd definitely buy a 0-60 that approached 5.0 seconds! On a cool, dry day with the water temp under 100, the car absolutely flies. Not that a 6.0 or 6.5 would be a bad thing, though...

Best of luck sorting out the Chip dilemma!

Hello.
I got another chip from quick chip this friday and I installed it. Sorry, to mention this, but it is not working right again. I don't know if there is something wrong with the car or the chips are not programed right to run with my computer.
The idling remains and the car will still acclerate itself, but the foul exhaust was gone.
When the RMP is at about 500-700 the car will idle for awhile, then then it will acclerate itself. Then the RMP will drop to about the same range (500-700),and it will repeat the same process.
I put the stock chip back in and I found all the idling and accleration problems are gone. The car was able to run as normal.
Personally, I think that the minor idle problem won't cost the (quickchip)chip to run like this, would it ? O2 sensor ?
Any suggestions or comments are welcome.
Pete

Lee,

I believe he has the ASR disabled some how. Other than that, the car is bone stock.....

Well, smooth intake tubes are installed,but I don't consider it as a modification....LOL

Try in a cool night, and see what your 500E is capable of...
