Help with understanding alignment of 4x cam and 58x crank reluctor wheels and sensor

[tunedportcj5]

Im pretty sure you can just go through and 0 the tables out and turn the DTCs off, my hope is the OS wont freak out when it doesnt get any feedback from the cam position sensor (hopefully killing the DTCs will avoid that). Id have to look again, but I think thats the only issue...

Thanks Erik... we'll find out sooner than later

JP, I guess I need to get a few pics up... I have been hesitant because its a trial and error thing and didnt want to represent any false info.

Let me know if you need a hand with the tune, I havent played with an E67 based I6 but Ive looked through the tune a few times.

Thanks Erik, I appreciate it. I have not spent any time with the tune yet - its going to be a fun one since there is not really any kind of base-tune to start with. However, it will probably be much easier than dialing in a 240/240 .650 cam...lol But again, I dont have too much experience with the E67 and the virtual VE. I've got a million hours tuning the 0411s though.

Coil pack arrangement

Side shot of distributor/cam signal. This is the OEM distributor housing with custom 4x wheel and vortec cam sensor. Not very elegant but I did not want to spend a ton of time and money on the first version without knowing for sure all of this is going to work. Once everything is confirmed and I know this project will be a sucess. I'll probably build something a bit more low profile or just buy a EFIConnection wheel and retrofit a vortec distributor base to the toyota shaft.

Another side/rear shot...

6" 60-2 electromotive trigger wheel. I'm not really excited about an external mounted trigger but it sure makes it easy to modify to get everything dialed in. Again, once everything is working and dialed-in, I'll revisit and install a Supra oil-pump housing which is setup for a crank sensor. 60-2 wheels are available for that configuration. Its just sitting on the crank bolt in this pic - its not mounted.

Custom sheet metal intake and 90mm TB. I should have it all welded out this weekend, its just roughed-in for fitment in that pic.


The following is already pinned/wired:
-ETC
-Cam Sensor
-Knock sensors
-Injectors
-Coils
-ECT
-MAP
-MAF/IAT

Remaining:
-Crank sensor
-T42 / GMLan
-Grounds
-All Battery/Ignition leads
-NBO2s

Question regarding MAP configuration... For the time being, I am using the stock LSx MAP. I'll eventually run a 3-bar MAP. I think I'd like to remote mount the MAP instead of directly on the intake. I'd prefer to use a barbed NPT fitting and run a hose to the MAP. Anyone see any concerns with this? I know that has been the standard on many vehicles for many years in the past.

Thanks!

Besides a full time 55-60hr/wk job, 7-month preggo wife, and a 2-1/2 year old. This project has been consuming most of my time. Thought I'd share....(Hey, it has LS3 with an E38 - it fits the forum)

Tubed front and rear chassis, full 10pt cage, 4-linked, coilovers

Dana 60 front, full hydro steering, 14bolt rear, 5.38s

16" Fox coliovers at all 4 corners

GMPP LS3 w/hotcam, TH400, Yank 2800, Atlas3.8

Griffin cooling... just wanted to show off the sweet mounting setup


Enjoy!

Cool project

Thanks for the pics! Looking good, makes me want to start moving forward with my project. So you went with the EfiConnection 4x cam reluctor wheel and an electromotive 58x crank wheel? I wish I could PM so I could ask you what you paid for the 4x cam wheel. Did they send the info with it that describes how it is oriented with the crank wheel? I asked them about it and they wouldn't give me much info and told me they didn't have time to answer any more questions I may have about my project. I'm thinking about adapting their 4x cam wheel to the distributor in my 250ci Inline six chevy. I don't want to drop $575 for the two wheels from them though.
How did you determine the diameter of your 58x wheel? Was that determined by packaging and nothing else?
I am planning the exact same build as you except I'm using an old 250ci chevy inline six and a Buick GN turbo..........with the electronics from an '08+ Trailblazer. Any sources for parts that you'd like to share I'd be grateful!
Thanks,
JP

I fabbed up the 4x wheel myself and bought the 6" elecromotive wheel off eBay. I dont have the exact details on the crank/cam orientation - but I have a good idea... I'll know more info this weekend and i'll be happy to share. Diameter of the wheel(s) doesnt matter... 6" or 6'...

I am also pursuing the same computer swap, but on a little different engine, an air cooled Corvair flat six engine. I am in the same boat as you all are, I don't know what the cam/crank relationship is at this time also. I put a graphing scan tool on a customers '08 Trailblazer, but without a #1 cylinder reference, I am partially still in the dark, I know where the cam and crank sensors come into play with each other, but do not know where TDC is, need someone with a 4 trace lab scope.... anyone in the SE Wisconsin area who owns one???? When I can find the pics of the graphing scan tool that I have (my Imac died, have to retrieve pics from backup, damn hard drive!!!), I will post. I am also asking the same on the IATN forum if anyone has a good pic of the relationship, there are some real lab scope guru's there and hopefully someone pipes in and comes up with a pic!! I will keep all posted if I get anything!!!
