Project Sleep-R - Bedlined 79 RX7 Turbo 5.3 fun

[Burntz]

Yes Iv been tuning in open loop, as soon as I let it go into closed loop it idles stoich just fine. Its extremely annoying. Im having it tuned in a week, but the closer I can get it the better. I started back with my base tune and kinda back to square one. Idles very rich. Only leans up to about 13.5 reducing VE super super lean. Tried adjusting injector offsets, SPA etc with no gain. Put my min PW and default PW back to 1.1 because thats what the data says. Before with .593 it would start up really lean then go down to stoich for awhile and inevitably get down to around 12.5. I havn't messed with boundary timing yet but Iv read it can be raised with good results on bigger cams often?

Should I try adding some timing? Is there anything else I may not know about really that could help? Try disabling pretty much any modifier table? ugh

Heading down Saturday to KC to have Justune tune it. Crossing fingers for 600+

[Burntz]

Tuning at Justune went hit and miss.


*Had some issues with intake pipe blowing off and my MBC is kind of a pos.
*The car blows through the converter real bad. Thats top of the list for winter.
*Also my supposed 80lb injectors that I couldnt get to run right are acting like 60lb injectors. He tuned them as such and they ran right. Dont know what the issue is there.


But at one point when it hit 13-14 psi (on accident) it made 503whp. Kinda low but converter is probably killing it.
Turned it down and made 410whp on 8 lbs. Then developed a boost leak I need to track down. Gonna get it all sealed up and leave it at 10lbs. Hard to dial it in with that damn MBC.

Plans for winter are:

*Custom built quality converter from PTC or Neil Chance
*Re-do harness.
*Ls6 intake or better.
*Maybe a EBC depending on what kinda cash I can save.
*E-85 if I have the injector for it, 3 bar map, and moar boost.

Glad to see more progress on it. The fact that it would not idle stoich in open loop was really stumping me. The injector situation clears it up though.

E-85 should be a good move for you. Ever since i began using it i never looked back and at $1.55 a gallon I can't complain

The big regulator valves have worked for me as a MBC.  They hold boost very solid and adjustment on it is real simple.

A quick band aid from now until you get your new converter is to run Tractor fluid on your transmission. hygard oil will tighten your converter up a bit.

Thanks! Your help has been valuable the past few weeks. Hope to get the boost leaks fixed by tmw and go play around a bit.

[Burntz]

No boost leaks but found an exhaust leak. Doesn't seem like a super bad leak but under boost and hotside backpressure I could see why its not pushing the turbo past 1psi. Gonna fix tomorrow and hopefully be back to 10lbs.

Also welded a lip around my throttle body and welded the intake pipe crack.

Car runs and drives great. Felt good to really drive it again.

I hope to actually see your car in action someday.  It sounds like you are making good progress.

If you need some closer dyno help, 402Dyno is just North of Elkhorn.  It's a Mustang dyno, and being run by Jered Klug with some assistance from Tom Van Vugt.

[Burntz]

I've messaged Jered many times and he never really gave me the time of day. I offered to pay him half to help me get a base tune on it and driveable and then i'd bring it up... and half the time he never even messaged me back.

Chad at The Shop Inc has been extremely helpful. Messaged me back a ton, let me borrow a cable, had me come in and showed me some things in Hp Tuners when I first got it. Quality stand up guy. Unfortunately he's so busy lately that he didn't really have any time to tune the car until next year. I heard good things about Justin in KC so we loaded up and headed down. Plus he was cheaper then both Jered and Chad and is going to give me email support to fine tune the driveability.

I have heard that from someone else.  I will have to bring that up the next time I see him.  Can someone really be so busy that they turn away business?  Glad you found someone to work with on doing your own tuning.  I thought about going down that road, but I just don't want to dedicate the time and effort.  My laziness continues to grow every year.

[Burntz]

In the end its all good. I wanted to have Chad Fegley tune it but he just wasn't going to be able to get me in until next year. Justune did a great job.

Found a blown coupler off my IC that was so bad I couldnt even really hear it haha. New couplers and t-bolts wont be here for a week... so i fixed it with duct tape and a clamp. Its holding for now! Ghetto to the max but Iv only got a few days left to enjoy this bad boy till its in hibernation.

[Burntz]

Ran a exhaust only ls1 camaro (maybe a cam too, seemed faster then it should have been) with drag radials and put 4-5 cars on him while I was pedaling the whole way down the track trying to let the converter catch up. First race on the new combo and was fun.

Then I raced a mostly stock Cobra with a upgraded IC pump and some other cooling stuff I guess. He said he dyno'd 420whp. It was even worse for him as I launched alot better and just kept pulling. The car is faster at like 80% throttle than 100% throttle in 3rd as the converter catches a little bit  . But it went from being a dog at the end with a stock cam and nitrous to wanting to pull like crazy on the big end. I love it.

Shitty snapchat vid:

Race a turbo mustang GT in the 1/8th and he put a car or two on me. Way bigger tires, trans brake etc. I was coming around him when he shut down since his 3rd gear is out.

Also raced "sketchy vert". Procharged trans am that some people have probably seen on 1320video. I had him out of the hole a car or two and was holding him off barely until the back half and he came around me pretty hard before the 1/4. To be expected when he's making 400hp more than I am 

She'll probably go into hibernation until next spring now. Definitely needing a few things for next spring.

Wheres all the video? We want to see and hear this thing!

Got a turbo converter laying around forcefed?
