Wow you are doing lots of fun stuff! That LS1 for the RX8 is really going make it scoot down the road!

I am wondering if you have tried contacting tech support regarding the wiring./issues with the new EVO pro unit.
Their email address is: [email protected]
The website with phone number/support is here: https://www.diyautotune.com/contact-us/

Yes, my son has their numbers on speed dial, lol. But thank you for the numbers. I may just try a call to see if I can get on top of the wiring questions myself. My problem is, if they start getting too technical I'll get lost in the verbiage real fast. Me and electrical do not play well together. I really appreciate the support and kind words though. I may actually get this thing running before I'm too old to drive it. Ha.

Hey guys, just an update. Well----sold the RX8 because I got twice what I paid for it and I was worried if I could get it to meet emissions once I stuck all the time and money into the LS conversion and not make it legal. So I used the money and added enough to pick up a 2002 Camaro SS/SLP last of the kind 6 speed. The SS will get the LS I'm building once it'* completed. I just brought the engine home once the block was cleaned , one cylinder received a new liner, line honed and the bore was finish honed for the JE pistons it will receive. I found a set of 4th gen 4.8 6.278 rods and had them gone thru completely and rebuilt. The 4.8 crank was already magnafluxed and polished so that is ready to go, just need a key way cut on the snout so i can add a ATI balancer. Once I figure out the head I'll be using, the block goes back to the machine shop for decking. Normally it is said that you can not use LS3 heads on a bore smaller than 4 inch. My LS is at 3.905 and the big 2.165 intake valve does fit fine.The original 1.59 exhaust still will not clear the cylinder wall, but a 1.55 just does. I plan to see how deep the valve has to go and if I only need a small amount of travel for the valve lift that will drop in to the cylinder, I maybe able to do a small scallop (grind out a divot) in the cylinder edge for enough clearance. Then I will use the 1.59'*. But if I can't I will look at adapting the 1.55'*. But I have to decide if that will restrict the exhaust too much to make the adaption worth it using the LS3 heads. I still have to mock it all up to make sure. If not I have access to a pair of 799 cathedral port heads that once ported should flow a full 300 cfm or more, to use. In reality the cathedral ports, even when ported could possibly be the better head than the ported LS3 rectangular port heads for this short stroke approx 312 cid LS. The ported Cathedral ports may still exhibit better velocity than the LS3'* and actually out perform the bigger heads. The LS3'* could make the bottom end just too soggy. I plan to buzz the LS to 7500-8000 rpm so I would like as much bottom end as possible and good top end to make it a good full rpm range motor. I don't want a "light switch". Anywho. Just letting you know what I've been up to.

The '63 has been started but the MS3 PRO EVO is having problems controlling the big 2000cc injectors. The car tries to run but as it tries to control the injectors it just keeps going a little bit farther out of range and then ends up shutting down. I do have an issue with one of the cooling lines leaking that needs fixing. Otherwise so far everything is working. Although the engine does not continue running so things may show up after it gets straightened out??? I'm hoping not. It'* too hot to do anything in the garage again now so I'm waiting for a cool time to drain the cooling system so I can get at the that leaky hose. But we're plugging away. I hope everyone is well and rolling along happily.
