Re: First time out with the TA61, LC1
 

*Ahem* For some reason talking to the trans guy via email is sort of like talking in Swahili. I should have remembered that asking more than one question at a time would result in only one or less being answered with great brevity. Maybe I'm just too wordy...

I'm a little uncomfy with the tuning right now only because I have an unproven trans, a new turbo, a fairly new (for me) injectors, a new(er) chip, a new scan tool, a new tool in the arsenal (WBO2), and the new (grounded) EGT probe seems to read ~200F over what it should via PowerLogger. And the shift points seem a little wonky. So it is almost like an entirely different car. I generally don't monkey with more than one thing at a time. Here just about everything has been changed, and I don't trust one piece of the puzzle. :willy:

Boost was ~25 PSI. The PL gauge was not completely zeroed, and read ~0.3 engine off.

I don't run alcohol. (yet) Right now there is a mix of 112 and 115 in the car. I think I should drain all or most of the tank, and put in 116. That would let me feel a little more comfy with tuning, as I wouldn't be so on close to the gasket-popping edge, even if it went a hair lean.

I think with better air and better fuel, I can get a little more out of it without pushing the injectors so hard. Might even be able to click the boost up a notch, and put the timing back in 3rd. That is certainly costing me top end MPH. However, right now my EGT is useless with PL. Maybe I'll try hooking the new probe up to the meter for the moment to see if the readings make more sense. And hopefully I can sort the trans out without too much drama.

Clearly, the 60s will be the way to go. But I might not make the switch overnight.

Re: First time out with the TA61, LC1
 

After doing some head scratching, and some calculations, I decided to go ahead and go for the 60# injectors and the street and race chips to go with them. Even if I can eek out a fair tune with what I have, it will be on the ragged edge, and it won't allow pushing it any further. With the larger injector capacity, I'll have some comfort in that part of the tuning arena.

However, that still doesn't cure all the issues. The low revving shifts might be a factor of the TV adjustment. I think I'd be more worried if it were spinning unusually high than if it were spinning lower than it should be. I know I was going out the back door at ~5200+ before with 26" tires. Not sure why I'm not now. Maybe part of it was just the air and the tune. The shifts at 4900 are not high enough.

The other issue is the TCC lockup. Both my initial run and the final run show it happening at 86 MPH. The chip is supposed to have it set at 75 MPH. All I can think of is (1) my VSS or speedo gears are way off or (2) the chip is set up incorrectly. The tires are 26", so its not a factor of running huge tires or anything like that. I inserted a gear from another TR trans in this one, so only the drive gear could be the factor there. Still unlikely, IMHO, as it is a TR core. So, perhaps it is in the chip...

So, time to tear into it. Peddle some of the pieces. Wait for more goodies to show up. Hope things improve...

Re: First time out with the TA61, LC1
 

just a FYI, Ive found that locking up the TCC at 100MPH seems to work the best for me

On all the cars i tune / build for others and myself i have Eric @ Turbo Tweak set this up in the chips i order.

Re: First time out with the TA61, LC1
 

Well, the track prep explains some of the 60'. The Precision housing explains some of it. All of the street radial cars tearing up the line explains some of it, too.

I'm not going back with the old combo; the turbo has been sold. Plus, just have the itch to finally get going a bit faster. That TA49 had been on there for about a decade. It was time to give something else a try.

Given that it made ~470 HP on the dyno, and ~600 FT/Lb, I think any issues are bound to be more in the details. Or the driveline.

Re: First time out with the TA61, LC1
 

No, I didn't use a generic chip. I used a chip from a source other than the one I've used for the vast majority of the time I've had the car. Some of the behavior is different. Trying to get used to that. And some things, such as the EGT, had to be changed to mesh well with PowerLogger.

Anyone who things everything is "simple" or "plug n' play" when it comes to modifying cars needs to get a new hobby. If you want the most out of it, you need to give everything time and a lot of attention. Almost nothing is "plug and play", especially with something like these cars.

Re: First time out with the TA61, LC1
 

Scott, You say the lock up isnt firm, I wonder if it has the aux. lube tube installed and sealed in the pump?That would explain the rpm isue.I went 11.20 with that turbo and 009s.Was at the limit though on injectors.Will try and go next tuesday, they are closed this coming tues.I had bad air also last tuesday but still ran 10.60@127 on 19 psi with bad short times 1.61.
dday ps I didnt know Ken was still around have not seen him in years!!!!

Re: First time out with the TA61, LC1
 

That's a good call! The whole aux tube thing on those converters can be a leaky nightmare if not installed right. I also went 11.20 with that turbo and 009s as well!

BTW, still around ... been a long strange trip, but still here!

Re: First time out with the TA61, LC1
 

Lockup always had been firm. Always had felt like it just shifted into a another gear when it locked up. Lockup at full throttle was like a kick in the kidneys. As of late (this last trip to the track), not so much. However, the pan has been leaking. Maybe, the level was down a bit. I checked the level, and it is hard to tell. And with this custom deep pan and the rear draw filter on the tube (Chrysler filter?) I figured it really ought to handle being a hair down on fluid without sucking air. :dunno:

Can the lube tube be seen with the pan off, and without pulling the pump out?

The trans issues have kept me from getting track time a lot over the last few years. Had a lot time to be at the track, and a lot of issues with equipment. :ow:

I still have the last one David built on the floor. Has 25k on it with no problems. Kept it that way just in case...

Re: First time out with the TA61, LC1
 

You dont have to have it read full like a stock pan will read.
dday

Re: First time out with the TA61, LC1
 

The tube is on the backside of the pump and you have to pull the pump.
