Re: Trouble codes
misfires...possibly due to the lean bank. I'd look for a spark plug/wire/coil issue on that side.

Re: Trouble codes
Also check your grounds, and random ground not being attached will do some crazy things.

Re: Trouble codes
Also, I'm not trying to scare you, but my Camaro randomly through that P0300 code a while back. I couldn't figure out what was going on, and eventually I pulled my valve covers to find I had a few broken valve springs.

Re: Trouble codes
John said the problem might be the 80lb injectors. ...he also said my tune was unlocked. Does that mean I don't need credits from HP TUNERS to update the tune?
|
Re: Trouble codes
Unlocked means that others can look at and adjust your tune. Some tuners lock it so no one can see what they have done. Also the credits bought are registered and only good for the person using hptuners to do the tune. If you want to tune it you would still need to buy/use the credits so it can be registered to you. At least that is my understanding. Different people all have to pay independently.

Re: Trouble codes
There is a cost for the credits to unlock the pcm from the factory, essentially making it open (not read only). That cost is for the individual to pay a tuner.
Then there is the cost of the software itself. That is usually a cost the tuner pays as an investment in a tool, and charges his fees' to each individual to recoup costs and make a profit. This is a not a set amount. There are two main versions of the software from what I can remember., 1. full software and box for around $550, comes with credits for a few vehicles (i think 5, keeping in mind some different vehicles would use a non-standard amount of credits). 2. Is around $750 and is the "shop" version, which includes a ton more/unlimited credits. This one costs more up front but pays for itself by waiving the need for recurring fee's for credits. IF you plan to do other peoples tunes, this will pay for itself around the 5th tune. |

Re: Trouble codes
More than likely your misfire is due to the custom grind cam. When speartech built my harness and initial tune they did a horrible job of giving me a start tune. I told him all the specs of my motor(you can see in my sig). And he sent me a tune for an ls1. That could be what's happening to you. John Weeks got it worked out for me though.

Re: Trouble codes
Oh and to answer your question. The springs I broke were from Texas speed I bought them new and had them installed with my cam at Texas speed. They were less than a year old and had around 11,000 miles on them.

Why such a big injector? It would be all but impossible to tune this combo thru mail order. |
Re: Trouble codes
That 6.2 with a tvs would probably be using most of some 60's, IMO the 80's would be the next step up I'm used to seeing.
That said, I agree with you on the mail order issue. So I harp once again...go to a real tuner. |

Scan it with HP-Tuners & report back with the codes, The Generic scanners your using may be giving false info. |

As far as the cam...its been great with this motor though it made more vacuum when it was carb'd. The idle is lightly lopey/choppy and it jumps when I hit the go pedal. :lol: The HPTuners will help you identify problems with the scanner then correct them with the editor. Plus with the forum communities....a lot of folks running HPT (and some running boost) will be willing to look over your scans and tune...and make suggestions. Some may actually be helpful. :lol: |
