getting a conversion to run for the 1st time.

[98hc4mula]

Want to make sure that the current tune is able to get the car to run in order to eliminate the tune for the problem I am having with not starting. it cranks and cranks and eventually turns on for about 10 seconds and searches for Idle then dies.

please look it over and tell me if it should be able to at least idle.
thanks

can any one help me with a base tune in order to get the car to idle and turn on for the first time. I was told that the PCM was tuned in SD but I am debating on flashing in a stock tune and go from there for the set up I installed.


the PCM is a 2000 camaro
6.0 Lq4 with 227/243 591/588 114.5 lsa installed dot to dot.
stock ls1 intake and fuel injectors.
headers.
TH350

if anyone can guide me in the right direction I would appreciate it. I am reading up alot on how to tune my own car and just got HPT in my computer. I hope to learn a lot from this site.

thanks
David

Post the tune, you'll get more interest.

[robbyredneck]

don't bother flashing it back to stock ,leave it sd. if you license it sd and convert it back to maf it'll cost ya. start by changing the displacement and getting a wide band in the mix. then post logs and tunes when your ready

[98hc4mula]

I will copy it today and post it. The thing is I cant get a log bc its not even staying on for longer than 5-10 seconds and I have to keep cranking it for it to start.
I wanted some help on a base tune to get it running.
the car does have a turbo cam but I dont think that would be the issue. it should at least idle....rough but idle.
the cam is a 227/243 591/588 114.5 lsa installed dot to dot.

I would start with what robbyredneck wrote. Change the displacement and hook up a wideband. Take a log from the startup. This will help people to help you.

[98hc4mula]

ok cool, I will do that as soon as I receive the WB...thanks for the suggestion.

[98hc4mula]

I rdered the AFX w/NTK sensor WB so I can start data login and on my way. what do you think of this WB? is it easy to set up and is it mobile from one car to another?

[robbyredneck]

its what i have and i love it

[98hc4mula]

sweet, cant wait to get it and wire everything up.
can you tell me if the WB is able to be moved from one car to another with out any difficulty?

[robbyredneck]

two wires and a bung. its really easy to move depending on how well you hide the 2 miles of wire.

I edited the post to include the current tune in the car. I am interested in learning if the tune would be able to let the engine idle. I am trying to eliminate the possibility that the tune is at fault. I am basically diagnosing if everything is set up correctly for the engine to run. right now im about to check and recheck all grounds, fuses and coil spark to name a few.
thanks

[98hc4mula]

well, i placed a test light on the pink wires on the coils and found out that the PS coil pink wire is not getting power. only the DS is getting power.
I need to figure this out before I can attempt to start again.
all fuses are good.
PCM bat
ENG sens
PCM IGN
IGN
STRTR???? should this power the test light with the key on the ON position?

[BlackZJ]

I can't help you with the wireing but I saw something in the tune, which should be changed. You should set Engine>>General>>Cylinder Vol. -> 0.75

pink should be hot koeo

boy, two good pieces of info. good find on the coil pack wires. it looks like its kinda setup for maf also. all the maf values are there except maf fail in diagnostics is 0 and dtcs have been modded. i would download from the repository a stock ls tune and a 6.0l tune just so you can use the compare feature so you don't get off track. your going to have to keep an eye on the o2 once you get your electric sorted out and don't be suprised when your cold start is really fat, it should be. good news you won't have much dicking with your injector data to do, bad news is the ve will need tons of work.

[98hc4mula]

seems like I have a bad connection on the grounds. they did not have any continuity on the grounds at the plugs by the coils. I will check their connections behind the heads, below engine mount on DS, by the starter. and all body grds.

[98hc4mula]

well I probed and probed all evening only to fix the ground issue. the other problem is that the PS coil still did not have any power to the pink wire. I ended up running a wire from a switched 12v to that wire so the coil on that side have power to at least start the car.
still need to figure out the wiring though.
I am out of ideas with that for now. need to do some research for that since I dont know where the coils draw from on the PS.
the car idles and stays idling by itself but chokes if I give it a little gas.
I am going to wait for the AFR sensor to hook it up and get some logs to post.

The only thing you can do without the WB is to let the engine warmup in idle (to warm up the NB) and look at the mV of the NB. If they are high (800+mV) you are rich and if they are somewhere near 0mV, you are lean (which I suppose you are).
You could try to push throttle only lightly, watch what the NB are showing and correct that part of the VE map. Though it's not perfect but it could guide you in the right direction so the Engine runs and you could tune it a bit with the LTFT or STFT.

At least that's what I would do, if I couldn't wait until my WB is here.

See if this helps you out with the wiring.

Good luck

[98hc4mula]

on the diagram above. the s19....where does it go to?
seems like the pink wire is a direct wire from there to the coil plug.
