So whats the final verdict on this chip? There are some TL-P guys looking to get a gb going w/ Unichip. That is of course if its worth it.

So all impressions/dynos welcome. Any help would be greatly appreciated!

Thnx.

 

Have the chip custom tuned bottom line.. IMO.. I would not allow them to do a pre-program for each car.. We had the option of buying just the chip and have it custom tuned but were not aware of it at the time..

Basically Alot of of were having trouble with CELs and rough idling... The biggest problem was the A/F ratio being out of whack..

Every person that has had a good dyno/experience has had the chip tuned in one way or another..

 

What Jon3si said. Have the chip tuned.

 

And if you plan to install a CompTech S/C, don't bother with the Unichip, regardless what Unichip may claim. I've been there and done that. Basically, the Unichip is not compatible with the CompTech S/C kit.

 

Also check to see if there a is Unichip dealer near you to tune it. Unfortunately, the closet one to me is in Chicago, so I'm kinda stuck.

 

def need it tuned

 

i got mr steves and he had his dyno tuned and my car runs great with it. no idle probs and i never throw any codes

 

My Unichip is still collecting dust. I've been too lazy to put it back up for sale. Never installed it - never tuned it. Wish it would work w/ my blower.

 

Fa-get about it - the Unichip that is... According to Shad at CompTech, as soon as he finishes re-mapping the '04 TL ECU using the replacement device for the ESM, they will begin to work on retro-kits for the older CL/TL S/C kits. Well at least that's the plan - hopefully by late spring.

 

i'm working with unichip right now on a SC version of their product. my car is the test mule. anyway there still working out the details and a new map should be out pretty soon. i dyno with SC w/HBP, headers, and mugens mods at 284whp. after the tuned chip i was exactly at 300whp, a good increase of 16 horses. and when using 104 octane i was at 320whp.

 

01 cls (cai, headers) i have tried to get rid of reoccuring cel's over the last 8-10 mo.s without complete success. i have decided to have the chip custom tuned as numerous remapped chips sent from unichip and trial installed have not solved this problem. all other problems i've had with the chip/harness have been solved with the current install. (the code tripping the cel"s is: random misfire of one or more cylinder(s) when read by a scan-tool)
re: impressions... 1. car is more responsive in low-midrange rpm and power is more linear up thru redline. 2. slight increase in fuel mileage. 3. i believe a portion of the chip cost will be saved thru improved fuel economy.

 

inpressive, u have any track #'s

 

report back after you get it tuned. how concerned are you about the random misfires?

 

not yet since the track closed for the winter here in portland. i just got this done last week and is still working with unichip because the car seems to ping alittle when hitting vtec.

 

I am probably going to be geting a few mods this winter break- headers, intake, exhaust, DvD screens. And I was wondering about the unichip. I have read about the benifits, and in doing so I read that Mr. Stve adn others suggest getting the chip tuned to the car. I live in NC and I belive the closest tuner in Gathserother,( dunno) MD. I am willing to drive up there to get that done, plus I have a lady @ howard I would love to visit. I was wondering how much the chip costs and the additional cost of getting it tuned. Will the tune be a 1 and done, or will it require periodic adjustments.
Thanks for the help in advance

 

^^Should be a one and done until you add more mods.

 

I'd like to see that. Although hearing that you have pinging really worries me. All it takes is one or two instances of detonation and your block is history. I saw it yesterday at my dealership. '03 CLS, automatic, S/C, totally destoryed rear bank of cylinders. Needs a new short block.

I made 295whp without any tuning. I should be getting the E-Manage prior to New Years and i'll have that tuned up.

 

darrinb & mike,
will have track #'s after (down to chicago ) tuning in spring. Re: misfires, not too concerned as only occur now above 6.6k and car wont see those #'s til after tuning in early april, if however cel's continue then i will probubly remove. (note: as a control i removed chip prior to each trial install , did idle relearn, took to redline, 3 wot runs. no cel's on stock ecu)
i will repost in spring.

 

Be careful there as I know what they are doing. You are relying on significant fuel pressure and then reducing the MAP signal to lean it out. You will hit a wall which will require additional pulse width (not available with the Unichip), larger injectors and still very high fuel pressures or additional injectors.

There is a reason why the most powerful J32A2 engines went the route they did.

 

your totally correct steve. i spoke with tony @ unichip yesterday with this concern and he said that additional hardware is needed to be able to add fuel. i unplugged their system right away. e-manage is way to go! thanks steve

 

Ouch, another kick in the nuts to UniChip. It's a shame their product didn't work out for the majority of the TL/CL crowd. The guys over there are extremely helpful.

 

I just had to take mine out when the temps went below 35 degrees. On start up I would throw a CEL that read as Cylinder 1,3,5 misfires. I remember talking to jack when we were first having problems with the chip. He said due to our car being so sensitive to temperature that the chip might have to be remapped in winter time. At the time I was like yeah what ever, But now my car is telling me yes. I guess it's just a summertime toy

 

I was thinking about taking it out for the winter too. I think I'm not getting enough fuel.

 

i have had no probs so far :crossedfingers: :knockedonwood: due to cold weather

 

Mine is for sell. I had it in for few months and never had any issues. No CEL's and no misfires. I took it out the last time I had to bring my car to the dealership and have not put it back in yet. It is in the origianl box with all paperwork. Email me if you are interested.

I had mine custom tuned and it has never thrown a code. After the custom tuning the dyno showed a gain of about 4-5 whp.

IMHO, if I had it to do over again, I would not purchase the Unichip. Then bang for the buck is just not there.

 

That sucks, I am sorry to hear about the minimal gains Dennis...
