Cable Throttle body vs DBW I have an ly6 Im getting ready to swap into my Malibu. Im planning on using the E38 ecm, I have both a DBW and DBC throttle body. So Im curious can the E38 ECM be programed to work with a DBW throttle body? I ask because Im using a 700r4 and it will be challenging to figure out how to get the pressure cable to be pulled under throttle with a DBW throttle body. I can also save on the cost and time of installing an electronic pedal in the car? Anybody that has come across this please chime in. I want to install the engine this winter and right now next on my list is engine control.
Some reason you are stuck on the E38? You can do it, but your tuner needs to be sharp enough to make it happen, as the IAC, TPS etc are in the DBW throttle body....

The LY6 is a 58 tooth reluctor. Thats kind of why Im stuck on the E38. I know I can get a 24tooth PCM like the 411 and run a linenfelder box, but Im not that confident in those boxes. Ive heard some mixed reviews on them. Some guys never had a problem and some have had nothing but problems. I want to be able to put the family in the car and drive 250 miles to NY and not ever even think of it. If you know what I mean,
Thanks

I've seen people try a lot of different ways to get a tv cable hooked up to a DBW engine, but none of the are ever anything that looked like it would go the long haul. Personally I'd get an electronically controlled transmission to run behind it like it was designed for, then you could actually put the family in it and drive it anywhere you want and not have to think about it. Just my opinion anyway.

I know you probably have the 700 already, but you are leaving so much on the table by not running the electronically controlled trans. You can tune just about every aspect of the trans. I have mine tuned to where I can literally shift it with my foot during part throttle driving.......no BS...

You hit the nail on the head TomM. If I try to source another trans, Ill want to get a good one or have one built. It will set me back further. I have had this motor for 2 yrs already and I need it in the car this fall. A swap to an electronic trans isnt out of the question, but I can do that later. Ill try to make sure the harness has the plug for it. So for now I need to figure out how to control the 700r4.

I tried finding this tread but I had no luck. If you happen to remember who wrote it or anything els about it I would really appreciate it. Thanks
Plenty of people want to swap to a 700r using older engines. Sell your trans and get a used 4L60s. They are not super expensive and have the same footprint as the 700r. Do it right the first time and save yourself headaches down the road.

Another issue I have there is I have not heard good things about 4l60. Not stock atleast. My LY6 with hotcam is likely to over power that trans in a short time. The 700 I have was built for a big block. If I get an electronic trans I would like to get a 4l80 or if I go 60 I would like to build it first. Which I was hoping I can worry about later on.
I know you don't want to hear this again...but he's right.
If this thing is built tough enough to handle a big block, it should be worth quite a bit to one of the neanderthal's not into the LS scene yet.
Use that to finance your 4l60e...

I know you guys are right about getting a new trans. It kills me though because this will set me back yet again. Ill be giving up a built 700 for a stock 4l60, then if I blow it up Ill be having it done anyway. If I could just leave the 700 in there and work on building a 4l60 or 80 then I can put that in once you know.
Another thing to consider is the fact that no matter how built the 700 is, if you don't get the geometry right on the TV cable, you will burn it up in short order, seen it many times, then you dont even have one to sell. As for it being still in the car, that actually makes it an easier sell, people want to KNOW the trans works (take it for a drive) rather than just taking someone's word for it.
I welded a bracket to my DBW pedal so I could use an AR cruise module for my swap (the plug & play electrical modules didn't work). You could do something similar for the TV cable that the 700R4 needs (and for your cruise setup).
Just find an old throttle body from a 700R4 car/truck and measure the cable pull from idle to WOT. Then make the attachment arm on the pedal the needed length to get the same amount of cable travel from the pedal.
I did end up reshaping the stationary bracket to give me more toe room, but your TV cable would come from the firewall and could be the stationary bracket.
