On a side note, I took the high-z 46 lb injectors from the turbo V8 and put 4 of 'em in the TR7. That made a HUGE difference in how that car runs. Especially at and just off idle.  I had too large of injectors in the TR before, and they were causing several issues.

I put the rebuilt 2.3 injectors back in the Thunderbird and it is happy with them.

jcassity.........awesome troubleshooting write-up! Sticky that one!

If it was me, Gman I'd start at testing the solenoid valve. As Jcassity says, it needs to be OPEN when power is on ignition, so it is powered open and shut when power is removed. If it fails, then gases will not vent from the tank.

If the valve is good, go after the hoses and check valve tests next.

Just a suggestion.

I'm gonna drop that one on my wife sometime. LOL

Parts are ordered. Should be here in 4-6 days. Then I'll make a video showing how to build it and how it hooks up to Megasquirt along with the changes to make inside Tunerstudio to activate the output and how to change it to suit a 4 cylinder tach.

I struggled with GM style iac. Just unpluged it  same thing runs mint. Still struggling to get th 4cyl tach to work ill bother you in a little while for your mod to get the tach to work with the relay. I lost 3rd gear on the tremec. Getting some mods done now.



shiznit yeah. I promised you one about multiple times and never delivered. AArgh.

OK, I will I will I will get the parts and make one for you. In fact I'll make a 'how'to' video for Youtube and do yours for it. My local electronics shop shut down, so I gotta order parts.

I'll get it done.

This time.


Give me a week, then bug me mercilessly. Shame will probably work.

For the record, the issue with the Dakota fan controller was water intrusion onto the circuit board and a failed resistor. I used the water injection circuit on the breadboard I built long ago and used it to control the high speed fan and it is working fine.

Thanks, man.

Did you get that Megasquirt sorted out? I never did get a good idle using a Ford valve on MS1. In the end I just upped the idle and run it open loop for cold start. I threw in the towel after a LOT of messing with it.

Why did you take out the Tremec? Problems or making a change?

Hey, Jim. Glad to see that you still have this. It's been a while!

Hi Chuck. Yeah I still have it and the TR7 2.3 turbo. I took a year to swap back to normally aspirated due to laziness. LOL I also had some hand problems that are better now, so I can work in the garage again without pain. It sucks getting old!

Nice to see an update on this build.  Was one of my favorites.  Sucks that you had issues.  Did you ever think of getting a more suited turbo for it?  I did the 6.0L LSX swap in my 84 and will be adding a 7875 turbo.  The turbo I choose is a bit small but will hit all my goals easy.  Max power I want is around 700 at the wheels.

I did think about swapping turbos, but I decided instead to simplify the car. I felt that I wasn't using the turbo power much and with the new heads it has plenty of grunt.

400+ is PLENTY for a street car IMHO.

I got a Jaguar XKR with 400 supercharged ponies and that is perfect for me. You should get lots of grins with 700!

And the new overflow bottle location. I still want to get the A/C hooked up since I have never gotten around to doing it yet. I just need to get a crimping tool and make hoses to complete that part.

Hey peeps!

Man time flies. I've done quite a bit more work on the car. The turbo system is GONE. I think that Holset was an awful choice and was severely mismatched to the V8.

Since removing it the car runs 100% better and all my water use and smoking problems are gone along with it.

Removing the turbo, I had to get new proper V8 throttle and cruise control cables, re-flip the intake, re-do the fuel system, change injectors, remove the intercooler, relocate the PS reservoir, re-do the vacuum system, add a catch can, make a new air filter system, cut the turbo piping off the headers and flip them back to normal, add a Summit 2 1/2 inch H-pipe, buy and install a new dual exhaust (I used Mark V11 pipes and s) and totally re-tune the transmission and engine computers to match the new combo.

While I was at it I glued on the dash cover......it has been free-floating for years LOL. I also hated the fuel pressure gauge, so I pulled it off, relocated the O/D light and wideband button to the steering wheel console and put a stock clock back in. I like it a lot better now, especially at night.

I've been driving the car this way for a few months now and I like it a lot. Yesterday after pulling in to the drive, the overflow bottle began to puke out antifreeze. It turns out that the Dakota fan controller (or sending unit for it) has bit the dust. Today I'll be removing that and using the spare circuit I previously built into Megasquirt for water injection and re-purposing it to control the fan relay.

Cheers!

Jim
