So cool to see in this condition. My dad had the exact exterior. I believe he had a ‘83 and sold it in 1990. It was the coolest car to all my classmates when my dad picked me up. Love to see cruising videos with this bad boy. 👍
Awesome videos. Wish i was in Arizona. I got an all original '83 Camaro crossfire willed to me thats been stored and untouched since '92. Lets just say it has a few issues and no one here (Northwoods of WI) that knows anything about this car and I'm not really a mechanic. All ur crossfire vids are awesome. I wish you had more. I would actually pay for videos like you've posted or to get walk throughs on issues. My biggest issue now is it stumbles right at 1000rpm. Doesn't matter if im driving or sitting in park. It only does it at 1000rpm though. Thinking maybe its the ecm.
What a great video! I just picked up an 82 CE vette. Had a few TPI cars years ago, this is my first crossfire. I still have a 10.1 454 with LS-5 heads and a custom Clay smith roller cam in my truck that’s carb’s but I am really looking at seeing what I can do with this cross fire vette. It runs great now but I want to see what I can do to improve it while still keeping it stocking and respectable. Your vid’s are extremely insightful and very well done. Hats off to you sir.
@@Joesmusclecargarage a mechanic friend told me it needed a new computer and some head work . When I checked the computer it has some worn out connectors and lots of dirt and looks like someone tried fixing it and made it worse.....car runs good at times and really poopy other times
Been having timing issues and high idle. replaced the timing chain recently and that helped but I might have to rebuild the throttle body's....I think it might have vacum leaks.
@@manuelespana9016 Start by correctly setting the ignition timing, and doing a minimum air adjustment and TB balance. Finish it off with a TPS adjustment set to .525V.
Joe, great video, again, I'am catching up on some of your older videos. How do you think the 8746 ecm would work on my 82 vette? I have a EBL, but I could never get it working right. I like the idea of plug and play, I'm not at all a big computer guy. Thanks again
No valves are going to be burned. The Chrysler ELB cars of the 70s/80s ran leaner than 16:1. The 8746 is leaner in open loop. During closed loop operation, a stoich 14.7:1 is still maintained.
Hi, could you possibly send me the wiring harness diagram? I would love to do this to my 83 crossfire. If there is an email I can reach you at that is better please let me know. I really appreciate it! I want to keep my crossfire set up.
Thank you so much for making these videos. I love my crossfire and would like to keep the setup. Would you consider making a kit for the connection plugs pre pinned for the extra air sensor? I would buy a kit from you. If my code 42 problem is the ecu I would go the route you took. Great videos, keep them coming!
No problem! Glad they helped. I would consider making a harness for the IAT. I would have to make them per request though. I don’t know how much of a demand there would be for them to justify making a lot of them right off the bat.
@@Joesmusclecargarage if you are willing to make the harness, I'm willing to buy. I would like my car to run as good as it can, so let me know and I'll prepay with PayPal when the time comes. Thanks!...I'm really glad you have this channel!
hi friend have an 83 crossfire in restauration , i see on your movie you send files , shemas etc via email? if yes please im happy to get this to help me thanks very much friend!
Yes. As I stated in my videos, an 8746 will work in an L83 car, provided you have an L05 PROM. It would be easier for you to find a 7747 out of an L05 truck or van.
Hey Joe great channel. Love the TA and your no nonsense approach. I my self have an 82 vette that is stressing my brain. I have been having fuel problems for a little while now. I can crank the car cold and it runs fine. I can drive around town or just a little drive to my buddy's house with no issues. When I turn the car off, it won't crank. No fuel is going to the injectors. After 30 min or so it will eventually crank back up. Is this a ecm problem or prom? Don't even know how to get the prom flashed. The GM dealership says they don't even have the old technology to do it anymore. Your thoughts would be helpful.
No it turns over just fine, but I have no fuel going to the throttle bodies. From a cold start I get fuel and it runs fine. After I shut it off and try to recrank... nothing.
It will work without the IAT sensor if you use a 7747 ECM. The 8746 requires an IAT or it will throw the light. The two ECMs are interchangeable otherwise.
@@alexamos1862 Then I would make sure the connection at the EST wire is good. That wire being disconnected will cause the timing to remain at base timing and will throw a code 42.
Hey Joe...we texted a few weeks ago regarding the PROM to use with the 350...was it in fact the L05 you got in case you ever do the 305/350 switchover?
Yes. I found the NOS L05 PROM for $20 and free shipping. I doubt I’ll ever put a 350 in this car since the LU5 is the original matching numbers 305, but for the price I couldn’t pass it up.
Much appreciated...might get you to email me your data sheets...got to get the car out of storage first...unlike you it is not 90 degrees here in Ontario...no snow left but just above freezing today...keep the videos coming...can't wait to get into working on the '82 Vette...built my water manometer yesterday based on your guidelines.
@@Joesmusclecargarage Cool! The ecm in mine fried last night, started smoking like crazy, code reader wouldnt even work. CEL just stayed on and car ran rough. Might do this swap if i cant find the original
Sure thing. I will tell you right off the bat though the 5055 ECM is long out of production, and no aftermarket companies reman them. That’s why the 7747/8746 is the way to go, and HUNDREDS cheaper than an EBL/HAM. The part number for the IAT is 21091001 and is made by Walker. It comes with a new pigtail as well. One sensor wire goes to ground, and the other wire goes to pin C12 on the 32-pin connector on the 8746.

I did find the low hp problem it was the new tps needed calibrated and I had 3 fuel leaks.

Thank you for the post. Looking to get my 82 Z back on the road, appreciate the motivation.
Lots of work. Great job 👍
I have an '82 crossfire trans am thats all original with computer issues I'm definitely gonna try this now.
Would it be the same difference?
@@manuelespana9016 Can’t say for sure. All I know is the difference it made on my 83. What computer issues are you experiencing?

It would work perfectly fine, just as it does with any other 82-83 LU5 or 82/84 L83. As long as you have a 350 PROM, you’re good to go.
Thanks Joe, have a great holiday.
You as well
Thank you sir!.....appreciate the knowledge and definitely appreciate you sharing it!!!!!
I would like to do this to my 82 transam. Could you send me the diagrams and info to switch to the 8746?
i would be a little concerned about burning up valves due to leaner mixture, comment?
No valves are going to be burned. The Chrysler ELB cars of the 70s/80s ran leaner than 16:1. The 8746 is leaner in open loop. During closed loop operation, a stoich 14.7:1 is still maintained.

When you say it won’t crank, the starter isn’t doing anything? No click from the solenoid? Or is the starter dragging and cranking slowly?
No it turns over just fine, but I have no fuel going to the throttle bodies. From a cold start I get fuel and it runs fine. After I shut it off and try to recrank... nothing.
Are you getting spark when this happens? A bad/failing ICM will prevent injector pulse.
@@marcusdouget7710 i had the same problem with my 82 i changed the temp sensor on the intake and so far so good
Hi Joe will this swap work without the air temp sensor hooked up ? Is it just extra info for the ecu ?
It will work without the IAT sensor if you use a 7747 ECM. The 8746 requires an IAT or it will throw the light. The two ECMs are interchangeable otherwise.
Hey joe my 83 hasnt run right since I put the renegade on I have code 42 and less hp than the stock intake was gonna try a new icm.
Is your EST connected?
If it's the single wire connector there was alot of corrosion.
@@alexamos1862 Then I would make sure the connection at the EST wire is good. That wire being disconnected will cause the timing to remain at base timing and will throw a code 42.
Yes I confirm I had code 42 last days and I checkout the est wire.. it was loose at the battery link! Check it now
