Re: 58x ECM Conversion (E37 ECM, 58x crank, 4x cam, electronic throttle) All GM Gen IV ECMs require a TCM (Transmission Control Module) for electronic transmission control. The 4L60E uses a T42 TCM. A TCM must communicate with a compatible ECM through the CAN bus. GM TCMs are not stand alone...

Re: 58x ECM Conversion (E37 ECM, 58x crank, 4x cam, electronic throttle) Not yet. Several projects in the way.

Re: 58x ECM Conversion (E37 ECM, 58x crank, 4x cam, electronic throttle) Does BS3 support Gen IV LS-type 58x crank and 4x cam signals for V6 engine operation? (because I don't know)

Re: 58x ECM Conversion (E37 ECM, 58x crank, 4x cam, electronic throttle) Agreed. If there were a Syclone/Typhoon market for these throttle bodies, it would make good sense. I don't think there will be much of a market. This has the possibility of being no more than a one-off engine due to the...

Re: 58x ECM Conversion (E37 ECM, 58x crank, 4x cam, electronic throttle) You could have. We have a 3x crank reluctor solution for installing the 2007-up engines in 1996-up Vortec engines. The 1996-up 3x reluctor is about 4 inches in diameter. The 2007-up reluctor is more than 5 inches in...

Re: 58x ECM Conversion (E37 ECM, 58x crank, 4x cam, electronic throttle) The timing cover pictured is a modified timing cover. The sensor you see is camshaft sensor and a boss we machined and attached to get a camshaft signal from the face of the camshaft timing sprocket. The crank sensor...

Re: 58x ECM Conversion (E37 ECM, 58x crank, 4x cam, electronic throttle) I've not yet had my hands on a 2007-up 4.3L V6, but I do have some of the parts in the shop. The timing chain looks like it belongs on a bicycle and not an engine. I am curious to know if the 2007-up cylinder heads are...

Re: 58x ECM Conversion (E37 ECM, 58x crank, 4x cam, electronic throttle) A 4L60E or 4L80E would be required. Again...this is an expensive upgrade.

Hi Guys, I've posted previously about our intentions for a GM fuel management system upgrade for these engines, but this new thread is going to be specific to the 2007-up E37 ECM. About the E37 ECM Introduced with the 4.3L engine in the 2007 Silverado. This engine uses wasted spark and...

Re: injector wiring harness We make them http://www.eficonnection.com/eficonnection/ItemDetails.aspx?ItemId=1182

Re: Help with fuel injector selection Thanks for the Racetronix link. So one injector is $45.00, but a set of six is $330.00? The markup is $60.00 for a flow matched set? That's a bit much to ask for a flow matched set. No?

450-500hp engine build. Using SyTy intake manifold and fuel rails. Adjustable regulator. What injectors do you guys recommend and who sells them? Thanks!

Re: Brand New Comp Cams Camshaft Sold...pending payment within 24 hours.

Brand new Comp Cams camshaft pulled 12/26/12 from a 4.3L SyTy engine build by TPIS (December 2012). 210/215 @ 0.050 112lsa 4 degrees advance 500 lift flat nose I pulled this cam only because my build requires a step nose cam for a prototype camshaft sprocket we are working on for 4.3L/SBC/LT1...
