absolutely, as that changes displacement, compression, air flow, and volumetric efficiency, and VE Table is the mother of all tables

this is a great question but beyond this basic tutorial

Sorry for the late reply, school started back up and midterms around the corner.

I figured it would be a on the complicated side so this leads up to my next question. Would the getting the book from the tuning school be worth getting?

Thank you,

my advice to a 20 year younger self would be, digest / consume all the free information you can before dropping any coin on books or videos etc. these days there is so much free info out there, you just have to look, two words for you: Forums, Forums. Find a specific forum for your vehicle, or for your engine, or jump on the HP Tuners forum, cover yourself up in some thick skin, as some guys are jerks, and ask a bunch of specific questions, filter out all the BS and build away.

I have not used the tuning school materials so I can't recommend them.

I would suggest you consume as many YouTube videos as you can, but don't watch 12 hours worth in one day, watch an hour every other day, know what I'm saying, let your brain rest.

Here are some smart dudes that I enjoy watching. Oh, just because a video is not exactly about what you need, watch it anyway it may give you the foundation you need to build on, then you will find they all have 70% the same content, but it's that last 30% where you find the gold nuggets.

Yes I've watched some of these videos and barely understood 10% the first time, that's ok, there is a lot of information, so grab a cold one and watch them a few times, it's all good we all learn at different speeds, I applaud you for taking this on rather than [ahem] gaming, ha ha

In closing you will find a lot more dudes are doing write ups on what you are doing than what I am documenting in this thread, because seems like everyone wants to run before they can walk, ha ha.

I wish I was 20 something again lol, I'm what you call a late bloomer going back to college, still 30 years young.

is there anything to log when one is trying to start for the first time? I'm only firing on three cylinders. Coils are good and each injector is getting pulse(YAY NOID LIGHT).I need a new set of fuel injectors(3 are bad 37 ohms).

I'm trying to learn this VCM scanner and use it as a troubleshooting tool.

I looked at all those dudes videos and then some more. I liked this gentleman as well, very well spoken.

OMG, that was my first pick I just couldn't find the link to that first video at the time, thank you so much for posting this link.

sorry to hear about your troubles, did you disable your VATS, Vehicle Anti Theft System (I assume this is a Swap - engine not in original vehicle) I read that you say your coils are good, but does that mean you actually checked for spark, one plug at a time at the plug? (I like to use a test tool like the one below, wife prefers it too, so she aint standing in a puddle of water with metal vice grips trying to ground it to the block)

If you swap a good plug and its plug wire to another cylinder will it fire there? Will the bad plug / wire fire in the before working cylinder, on that coil?

A lot of times guys blame grounds, each side of coils has its own ground and the PCM uses four on these PINS: 1 and 40 on each of the blue and red connectors

Check out the link here: Grounds Demystified

Did you thin out your own harness did you repin any wires? sorry if asked and answered

which 3 cylinders fire? what do they have in common? are they all Odd or all Even for example, since the PCM has an Odd coil and an Even side coil

what codes show up in the Scan Tool?

did you check your fuses? even if they look good to the eye just replace the ones for the Injectors and Coils for funzies

No big deal, ill answer them all!

It's firing on 1,7 and 8.

Since we knew those three were firing, we did a rotation of all of the coils and wires to verify those were good as well. And they were.

We had a ground problem at the beginning, as it seems not having a ground hooked up will cause problems lol. I didn't have the ground hooked up for the coils. it is now.

Yes the harness is thinned out, but we didn't repin any of the inputs/outputs on the PCM.

I didn't see anything that popped out on the scan tool, but I shall double check it.

And yes sir, VATS is disabled.

could it be an airflow/fuel/spark

Oh and fuel is constant 58-60 psi with cranking

LOL, what else is there, ha ha - as an old timer once told me, unless you're trying to start a vehicle under water don't worry about the air, ha ha, focus on the other two, fuel and spark

I'm sorry I don't follow.

Scenario 1. you take a good coil/wire/spark from cylinder #1 and put it on bad cylinder #2, what happens there? does two fire or not?

share a pic of your fuse block or a link to your build please (sorry I don't show sigs on my forum view in case you have it in there) what is it out of Year / Make / Model / Mods I think you said heads, so I am assuming whole enchilada, did you swap injectors, did you decap them? if you built your own fuse block did some of our connections come loose?
