how did work out?

@@bigshotpep7500 made too much power for transmission to hold so waiting on new built one to come in rn lol

@@bigshotpep7500 and we ended up deleting knock sensors completely with the tune

Yes, use some oil to lube the tap

Honestly, you'd be better off selling the Gen3 and building a Gen4.

Thanks. That’s exactly what I did

How would I do that cause I feel more comfortable

@@mikeverything4098 it helps if you have a lathe so you can turn the threaded area down to the proper size for the threading die. It can still be done without a lathe, it just takes more time. Typically you'll hold the part in a vise and use strips of sand paper to work it down to size. I don't remember the thread sizes but that's easy to find online or from the Gen IV knock sensors you may have on hand. If nothing else you have the block. I've read conflicting information about wiring Gen IV 2 wire knock sensors into a Gen III ECU that expects a 1 wire sensor. That would be ideal but so far I haven't seen any certainty about it working. Good luck with whichever way you choose.

I was thinking about re-threading the knock sensor as well to make it smaller.

@@colingoede5705 on the side of block

@@renaissanceman7145 Some info I have found during my research, not sure if correct. Note it appears knock on Gen IV also pulls throttle position (electronic throttle) on knock, not just timing. This is what efilive shows: "The PCM can be used with two types of knock sensors, this parameter allows you to select which type of sensor is fitted to the engine. (This is available in HP tuners so seems to be correct) The standard LS1 sensor is a resonant type, these sensors are connected like so - Sensor Bank #1 - J1,pin51 Sensor Bank #2 - J1,pin11 If the engine is fitted with flat response sensors (like the LS2 uses), then the connections are like so - Sensor Bank #1 GND - J1,pin49 Sensor Bank #1 Signal - J1,pin09 Sensor Bank #2 GND - J1,pin50 Sensor Bank #1 Signal - J1,pin10 Part number for the new flat-response sensors: 12623730 Adaptor harness: www.amazon.com/dp/B082WMTSN5/ So repining the sensor signals needs to be done: Sensor Bank #1 Signal - J1, pin 09 - was pin 51 Sensor Bank #2 Signal - J1, pin 10 - was pin 11 Change sensor type in ecu - then change settings - to what?

Me too

Honestly I'm just lazy and not wanting to take the manifold off but didn't really think this would work and if its needing tune to change locations its not worth it unless your doing a engine swap or whatever the case may be.

You would have to remove the crank and install a 58x reluctor. Options are: • Install 58x reluctor on crank • Buy a gen 4 • Install holley terminator or other standalone that allows you to select reluctor

@@Sdpartscenter thanks. I knew the reluctor was different. I just wasn't sure if there was another way.

The only way is to swap the reluctor ring and cam gear to the newer style.

@@Sdpartscenter yall have the part numbers? That would be the true blessing

Caspers 109081 harness sdparts.com/i-24110029

@@Sdpartscenter will I still need this if I have the trg 002 from lingenfelter,if so will I need any other harnesses I have a 98 trans am with a ls1 going to put a l9h(6.2) ls3 conversion in the car

Will that work for a gen 4 6.2 engine i originally had a gen 3 4.8

?

A waste of money don't use them especially if you plan on using long tube headers it won't be enough room to screw in the knock sensors

@@jessicawatson-english5505 thats good to know

Can someone help me out. 7 months and still no answers , thanks

Are you always in power enrichment?

You can run this one, some of the early Gen 1 blocks did not have a damper or even bolt holes for installation. sdparts.com/i-24096350

Also what about the big sprocket? Do I use the 4x or 1x

@@ikemunoz951 use a 1x timing set for a 2005-2006 GTO, cloyes part number 9-4205S. I have been researching this as well and just found this information. I also found wire extensions on eBay for the cam sensor and the two knock sensors.

@@williamb2013 we should all make a lil group for gen4 in gen 3 I’m getting ready to finish up my build I used the 4x cam gear and the lingenfelter 24x-58x harness will I need anything else

@@mikeverything4098 I’m in the process of rebuilding an engine for mine. Putting an LC9 where my L33 is. Making a few changes, like a new 24x on the crank. Gas grill came in handy for that.

You can change the reluctor itself and have someone weld it.

Or buy a $200 harness from lingenfelter

The Lingenfelter box only works on 58x reluctor to 24x ecm. There is no way except changing the reluctor to use a 58x ecm.

If you go back to 58x/4x you will have to go back to the Gen 4 style knock sensors. Drilling and tapping the side of the block for the GEN III sensors is kind of a "final solution." If you're looking to convert back in the future, it may be best to rethink your current plans, or you'll have to weld up the holes and re-tap for the smaller thread when you convert back.

@@Sdpartscenter wouldn’t a helicoil work to get back to the original size?

@@williamb2013 I don't see why that wouldn't work. 👍🏻

Re-thread the knock sensor instead of the block..

Correct, it's the single wire setup.

You can't convert up the signals from 24x to 58x so you have to remove the crank and add a 58x reluctor wheel. For many it's just easier to sell the Gen3 and get a Gen4.

@@Sdpartscenter the ls2 for late models gto’s are 24x and use the side crank sensors.
