aww man. you got me so excited. that table still isn't there for a 17 camaro. i did download a tune for a 16 silverado with a 5.3 and a8 and sure enough it is right there but not for the camaro. i...

The diagram I have shows pin 22 is tcc b and is yellow/brown. I didn’t confirm it is pin 22 but I did tap a yellow/brown and it is the tcc. On the camaro you have to pull the front bumper to get to...

I found an article about solenoids and it said under 200hz and they are looking to complete open and close the noid. Above 200hz and they are looking to just move the noid a certain amount or apply a...

I enjoy this stuff and the extra ecm part of it really opens things up for getting creative. You could build/buy a tps triggered relay. The thing about the extra ecm is it has all the inputs so let’s...

More about the tcc lock up. I hooked up a scope and with bidirectional control the scope shows 63% dc and 3000hz. I can only get to 250hz with my controller. I think the resistor approach is going to...

There is no break out harness. Wires needed to be tapped in each of the 3 connectors to the ecm. I tapped everything right near the ecm. I was able to double tap most things. Cam, crank, tps(from...

I am running a ms3pro ultimate for a pile of extra features. Port fuel, ignition, speed based dome boost control, traction control, 2step, 3step, aux fuel pump control, intercooler pump control, dash...

Yes. I can use anything I want to trip that output, currently it is set at over 85% tps and over 45mph.

I did not turn off the lock up in the tune but I probably should at least at wot where this device is kicking in.

There is more than one yellow/brown in that bundle, you have to check the voltage on that wire and trigger the lock up and see if it changes. You have to get it up to speed to do that.

I did not...

I did call circle d today and ask how much hp I can expect that clutch to hold. He told me 1200-1300hp.

101624

With the scan tool showing 113psi of tcc pressure I was seeing 200-300rpm Of slip with about 600hp. I have a circle d multi disk.

With the bidirectional control I see 0 slip(+or- 20rpm on the...

I have a pwm output available on my controller. It can go from 10-250hz. I am curious if I can get rid of the resistor and hook it up directly to the output with a duty cycle. 250hz seems kinda low....

I made a few more runs last night. I didn’t have the tcc learn turned off and thought it might be the cause of my inconsistency’s. It is still very inconsistent. One time it applies pressure mid 3rd....

I am able to get some control of the tcc pressure. Just not as much as is needed to get it to completely lock up. I am also seeing about 200rpm of slip at my current power level(~600hp). That goes up...

The whole bidirectional control thing is sweet but it seems slow and not 100% consistent. Also I have no idea how you would do that. I currently have a stand beside ecm that runs a pile of stuff. I...

I am just looking to over ride it down the track. Maybe 6 seconds at a time. We’re they locking it up for long periods of time?

I could set up a pwm or variable voltage control pretty easy but a...

I have been told there is no actual pressure sensor. No idea what the actual pressure is. I am going to get busy trying to bypass the ecm and trigger it directly. I know I can get control of that...

I am trying to get control of my tcc pressure too especially at wot. It would be great if the tables had the desired effects. The bidirectional control is able to lock it up and hold a ton of power...

I care and am here to try and figure out a fix. Here is my post from another forum.

Anyone have luck controlling the tcc lock up pressure? The logged pressure doesn’t match the apply ramp...

I tried this.

I logged module voltage and stock it reported 13.6volts. After turning it up with hp tuners from 14.7 volts to 16.5 volts it then showed 14.5 volts on the log.

I didn't measure...

I am getting a backfire or two on the shifts. i am seeing negative timing numbers at the shift and i think that combined with no fuel cut is causing the backfire.

i have logs when it was stock on...

That is great news. Seems like this would make a voltage booster obsolete(saves me $400).

Volcom, I have an lt4 hpfp with less than 500miles on it if your in the market. $600.

I would log the low side pressure and not worry about it if it stays above 40psi. If it does drop below 40psi hit it with more voltage. Typically this meant a voltage booster but I just found out we...
