Cut dsp5 switch

[dordtrecht5]

Bought this truck and I found out tonight, since I had an extra minute, and found out that the dsp5 switch wire was cut about a foot behind switch and 6" outside of the ecm.

Questions:

1.) is it possible for the dealer to flash a stock file back into the ecm with the pins still in ecm?

2.) Can I solder a red and black wire back onto each cut end safely and restore dsp5 switch?

3.) Would anyone like to take a stab at guessing whether or not the tuning is still on the ecm/dsp5?

Yes, I'm disappointed that the switch wire was cut, but more disappointed in myself for not noticing first and calling them out.

On a truck that has been sold "as is," is there a law about what "as is" means? As is to me should be that all of the functions of the truck should be right and run like a vehicle should operate. I've had problems with the abs system on the front right and also found out tonight that the hydroboost is lleaking just a touch inside the cab. IMO that is not "as is". I had another thread about the problems with no response.

Touch the two wires coming out of the ecm together this will be the opposite side of the dsp5 like going from tune 5 to tune 1.
As is means the truck is sold in the current condition no matter what condition it is.

The dealer can flash the ecm even if the dsp5 switch is connected.

Just read your other thread....... You bought a 15 year old truck why would you expect it to be perfect?

I appreciate your reply.

I don't expect it to be perfect at all. They gave me the list and receipt if the things they did do to the truck in repair.

What I expect from a dealer is to be honest about what I'm buying. They said they fixed the abs issue. Its not fixed. The hydro boost is a safety issue in my opinion. The electrical issues that I am having with the cruise and interior lights is something I can deal with it pay a mechanic to resolve.

I guess, when I was test driving I looked under the dash with a flashlight and the hydroboost was not leaking, so I guess they could have wiped the thing clean and not worried about.

For the most part, I'm bitching because of disappointment.

I train horses. If I sold a horse as is, advertising it as "this and that", no matter the age, if the customer/buyer takes me to court for an issue because the horse bucked the rider off, or it doesn't do what I said it would do, I'm liable. "As is" in my world is mostly meeting the expectation, within reason, of the customer.

Ok...help me understand what this will do. I know it'll change 1 to 5, but help me know what this actually accomplishes and the benefit of it.

Will it tell me if there are actually 5 tunes, or if the stock tune is the only one flashed?

After touching the two wire coming out of the ecm do I just start it and see if she starts and runs?

Are you sure the wires are the correct pinout numbers for a DSP5 switch, also, is there any evidence of a hole for the switch.?

The switch is installed with a 6" to 12" pig tail behind it. It was routed between the steel frame and under the gauges.

There is also a pigtail stickjng out of the ecm. It was beginning to get dark so I didn't take the ecm down and open it up to check where the pins were in the Plug and I didn't want to take it out to the shop to work on.

The wire was cut with side cutters.

Its a socal dsp5 switch.

The reason for such disappointment is because I agreed to a final price and then the sales manager came in and wouldn't agree with it because of the amount of work they had done to the truck which included rear rotors and pads, ball joints (both sides but can't remember if it was upper or lower), and "fixing" the abs because "the abs light was on when it was traded."

I've driven LB7s before. This one doesn't run like a stock LB7, it's got some ass behind it and the throttle is way more touchy than a stock file, so I don't really think they flashed a stock tune back onto the ecm. It has thrown a code a couple of times driving it, but it didn't stay on for any extended period.

Also, the salesman knows the man who traded it and the guy who flashed the tunes. I asked him to call the previous owner to find out what tunes were flashed with the switch. Salesman gave all the information to me, plus the ole boy's phone number.

Really no big deal either way. Clear the ends on the pig tail and have someone flash whatever tuning in the truck you desire. Stock or modified tuning piece of cake. Find someone with a v2 or buy an autocal from whoever.

"As is" in whatever world mean as it sits. Even for you and your horses, if you sold someone a bill of goods and its not right. Then i would guess you wouldnt sell many more horses right? I can understand what you mean about being upset. I would be frustrated myself, but no warranty was stipulated in sale also. You agreed to that and salesperson did also. I would be more upset that a final deal was made and finalized with a hand shake then not met on the selling party's end. I would have walked away at that point seeing that as "A shady sale".



If you touch the wire togather it will manipulate the ecm to change tunes like you rotated the switch. Yes you can solder the connections. They are not coaxial cable. Also if you have the previous owners number why dont you call and ask him?

I misunderstood the dealer part I understand your frustration now. I didn't realize they told you the abs issue was fixed. Check the front wheel speed sensor connectors for corrosion. If they are clean jack up the truck and check the front wheel hearings by grabbing the tire at the top and bottom and try to rock them feeling for play. Obviously having a scanner that will read ABS codes will tell you where to start looking also.

You can connect the wire while running and listen for a change if any. If you don't hear one try driving it.

 

[dordtrecht5]

Thanks, men. I appreciate the advice and I'll give it a whirl today.

The abs issue actually caused a force lock 4hi in the transfer case once.

That tire slid on packed snow with the abs activated. I was approaching a left hand turn and once I turned left and got on dry pavement I could feel the front tires grab. I got into the parking lot, stuck it in neutral...didn't disengage. Wouldn't disengage until I put it in reverse and backed a few feet.

Weirdest thing I've had happen so far.

I've had the truck since October and have put about 3k miles on it.

Generally speaking, I love the truck. Just trying to resolve these issues.

I can see how there was a misunderstanding... No worries.

I cleared the ends coming out of the ecm and no audible difference while touching the two wires together. This afternoon I'll go back out and get some lead to connect the two pig tails together and take her for a spin.

I did look at the speed sensor connections...seem OK. Did notice some fluid on the inside wall of the tire though.

Does anybody know if the '11 hydroboost and master cylinder works on the '02? If it does I may go with that; if not, is a reman Acdelco hydroboost a decent replacement...or us there a better hydroboost in the aftermarket?

Why are you asking any of this of us when you have the previous owner's phone number? Call him, be polite and get the information you need.

BTW, cant a person just buy another DSP5 switch, install it in place of the cut one, and switch tunes again? Sorry....never had use for a DSP5 so dont know.

 

[dordtrecht5]

I think so...on the dsp5.

Been looking for his number. I'm not so sure if he'd know anything more than what I do...the salesman said he only had it for 6 months before he decided to trade it for a '16 Duramax.

I'm going to call him if I can find the number. However, I know he's not much of a DIY type of a guy...young and has money...he hires his work done.

He may still remember who did the tuning and all. Might even have receipts for the work done, so you have a starting point. Thats what Im trying to get at.

Also depending on how tune was wrote level 1 on dsp5 could be the largest or smallest tune. It really depends how the main table was wrote. It could have 1400 usec or 3100 usec lol.

You could always buy a new switch and wire it up.

I know who did the tuning, Tom.
Its a local guy that doesn't write his own tunes...he just installs other people's. He does some simple thongs out of his farm shop...lift pumps and gauges and stuff.

I appreciate your input.

Tune 1 was the smallest and went up from there.

Yah...I could buy a switch.

What is the way that the Edge CTS2 works with switchable tuning? That what I'll probably begin with and then add some analog gauges when I need them.
