And here's the steps on how to do it...

Hope this helps

so basically i can take off the tension on the belt and just rotate the cam sprocket? its there any other way i can make that tool? i dont have the battery thing.

O2 voltages mean jack under WOT. Your front O2 sensor did not hurt your tune at all.

And, the timing belt needs to be dead on. Having it a tooth off isn't helping your situation.

ok nevermind about the cam timing. everything is ok. i made a mistake. so my o2 voltage has no affect on timing? so when i get a wideband i should just tune insync with the wideband and dont even worry bout the stock o2? the stock o2 just has to do with part throttle cruise right?

Under WOT your car is in open loop meaning it really only needs airflow to look at.

Yes the o2's has to do with part throttle cruising.

 

[97gstnick]

oooooh. ok. thanks for clearing that up guys. so i just need my wideband then.

 

[97gstnick]

but ### if my o2 is reading lean? would the ecu pull timing? because thats what its doing since it is bad...

 

[97gstnick]

ok guys, i figured out what i am going to do. i have recieved a new credit card and with tax return, i have decided to buy a wideband, jm smim with 70-80mm tb, dsmlink or ecu+. now i have two questions, with hardcore experience to back it up.. what wideband would you recommend? plx devices, aem uego?

and the most important, what would be a better choice, dsmlink or ecu+??? i need some really good points to be brought up. thanks once again!!

Honestly, don't buy a wideband.

DSMLink reads knock, and I've tuned off of that entirely. They also have an A/F estimate that's *supposed* to be close to a wideband, but obviously I've never checked.

Don't get me wrong, I'm sure a wideband is a great help in the long run, and very very useful, but I don't feel that it's neccessary with DSMLink.

Just my .02 though.

 

[RedTurboEclipse]

the a/f estimate on dsmlink is "close" but not accurate.. for the guys who want to be as accurate as possible.. they will get a wideband with dsmlink.. i personally dont have a wideband with my dsmlink.. i only want 350 max awhp with my 50trim/dsmlink which is pretty much the low average for dsms these days..

 

[90blacktsiawd]

i have recieved a new credit card

Don't make that mistake. It's something you'll end up kickin yourself in the ass for a year from now.

Back on topic i don't think the idea of getting a wideband is a bad one. It's not required but it's definately in the nice to have catagory. It's never going to be something that's going to hurt to have.

You know this is and interesting comment. I was talking to a AEM rep the other day and he recomended NOT tunning with knock, espeically if you have balance shafts removed, aftermarket forged pistions, and prothan style motormounts.

the recomended ONLY tunning with WB and timming. makes sence when you think about it.

anybody else heard of this?

Ignoring knock entirely (which you can easily do with the AEM since knock control is an option) is a stupid thing to do for a street car. If you've a track only car and would rather risk wasting an engine to win the race then go for it. Then again track cars run on race fuel 100% of the time which is of a consistant quality/octane, not like the crap out of the pump.

This is not to say tuning for knock is the way to go, instead select a target AFR/Timing map and uses Knock feedback to grade your results.

I remember the story Dave Bushur told of one of his customers tuning his big-HP car on his dyno and blowing it up as he didnt' run a knock sensor at all

 

[sweet97]

Confused! What would I tune with? I have a wideband and can read the timing. Shoot for say 11.0:1 on 93 octane and get as much timing as I can? How would I gauge the results? mark

 

[97gstnick]

actually, so far im pretty dead set on buying the plx m 300 wideband with the ecu+. the ecu plus has alot of nice features and the dyno tune looks very easy to use and decently accurate. it may not have the exact hp, but it shows when you drop or gain a few. this is something that may make your tune a whole lot better!

 

[97gstnick]

ok, i bit the bullet and bought dsmlink. i cant wait to get it. i bought it off an "authorized dealer" on ebay. please tell me i wont be disappointed in dsmlink. i find one thing that kinda sucks about dsmlink, you cant tune for cruise. i want to tune for really good gas mileage.

 

[larsrya8]

i find one thing that kinda sucks about dsmlink, you cant tune for cruise. i want to tune for really good gas mileage.

You tune for the global fuel compensation and then DSMLink uses that in the same calculations for cruise that the stock ECU used. The only way to get better mileage would be to run lean. Besides, even if you were to tune for more gas mileage, the ECU would automatically add that fuel back in using it's fuel trims.

BTW, how expensive was it on ebay? I can't imagine it being any cheaper than buying it from DSMLink.com and still be "genuine".

Nick I am "link" shy myself so your results will be much appreciated. Cost is high but if it allows the user to tune an extra say 50Hp from a before and after scenario then it would be well worth the cost and in my case learning to use a laptop! Please let us know the results? Thanks, Mark

Was this "Authorized dealer" 1320 motorsports? If so that's the same guy i picked it up from. Your not going to be disappointed by your purchase. Alittle scared, for lack of a better word, to start messing with everything as there is alot more to play with then most are used too. But it's very user friendly, and the support you can get for it on their forums as well as this one and DSMTalk will help you get started. Finding someone around you who is familiar with it and can give you a hand getting started would definately be a good thing.

larsrya8 - I got mine for either 520 or 540 shipped off ebay right after x-mas. It absolutely IS a full version and latest version of DSMLink. The only thing i didn't notice, which may have been on the install cd and i didn't notice, was the instruction manual. This wasn't a big deal as i had already had downloaded on my computer anyways.

sweet97 - I think looking for an extra 50 hp might be stretching it a bit much. But getting much better drive ability, pending you tune it right, some extra power, some of the best and easiest to read logs i've seen so far is definatelt going to come from the switch with some good tuning. Not to mention that chances are your not going to need to go to something more powerful than the link for your tunng needs.

 

[larsrya8]

Yeah as long as it was from someone like 1320 I'm not worried. If he got it for something like $350 or something, then you have to wonder. Mine didn't come with an instruction manual either, but it may have been on the CD. I got the software and the manual from their website. The only piece of paper I remember was the instructions for the clutch wire.

 

[97gstnick]

i guess the company is called jkg motorsports. they seem to be legit. we'll just have to see... i have played with dsmlink and im getting pretty good at playing around. sweet97, ill let you know everything once i get it up and running. im going to use the hp calculator before and after i tune to give you a good idea of what i did.

 

[90blacktsiawd]

That's the only paper that came in mine as well.

If you get a legit name and password to the dsmlink forums then you got a legit copy.

[90blacktsiawd]

That was directed at larsrya8 who said the only paper he got was the clutch wire install instructions.

 

[97gstnick]

ok, i got dsmlink in the car now and havent even really began to tune. when i first installed the chip i turned my boost down to 17 from 21. it pull almost the same with just the chips base tune! i was utterly amazed. i tuned the fuel just a wee little bit and got a tiny more power. but im not going to do anything until i get my gm map sensor and a new stock o2. mine is shot and the car doesnt want to idle.
