    i would of zapped it with a mig after the 1nd time tho.
    look into nord lock washers. mine are still screwed on tight with the washers.

    if you haven't read about these heres a random thread about control arms loosening up and nord washers

    Welp got to the shop this weekend, still no power, electrican is busy apperently. Checked out the rear end and all the bolts are tight. Im starting to think the rear tire was moving back and forth and causing the clunk.

    One idea for the rearend was to use these locks. At this time i think the alignment shifted, tire is clunking. So ill get another alignment on it and see what occurs.

    While underneath i noticed this, cant tell if its gas or oil residue.

    New oem bracket broke
    20171029_140718 by euro2fast4u, on Flickr


    ordered a new one today.


    Testing the location of the afr gauge. Since i have a new cluster think this will be the best and easiest way. Build a small case for it and mount it to the steering column.

    Heres the gauge operating. My scale from lc-1 is backwards from what this one wants to see.

    I am not sure why it flickers, i hope its not like this when operating.

    So Dans coworker, Pete, who also works for Revo was in town this weekend from the uk. We got some good results on the e30's tune.

    Progression throughout the day on Saturday.

    I am ditching the innovative wideband, it gave us more problems then i would like.


    Pete got the car running like an oem car and its amazing. We made fun of my tune as it was done by a blind man. So thankful he was able to help clean the tune up .

    That's cool.
    can you share the before and after timing map just to compare?

    So basically your vitual dyno was bullshit.
    Do another one and see how much virtual power you're laying down now.

    lmfao yes i agree the virtual dyno is bs still no real numbers from the dyno. Im using it as more of a comparison. Before i did up the boost to about 15psi and the values are similiar to those now just the fuel is finally inline. I dont think we did much timing adjustment. I meant to grab to the computer and snag a copy of the tune.

    Im thinking of running one of these, or building a 1/4" restrictor plate for the turbo T4 flange to increase velocity, and decrease top end flow and tame the creep.

    gotcha. so you guys street tuned i thought it was on a dyno.

    btw the MS autotune works fantastic
    just smooth out the surrounding cells and you can get a perfect ve map.
    highly recommend you just pay the 100 bux or whatever it is for TS.

    That top map is with the autotune. were gonna blame it on the wideband for now lol

    Running BPR8ES plugs now.


    No real difference, still get a miss fire. Backed the boost down some until the plugs and wires come in. Does feel like its knocking at light loads high rpms.


    It appears mega squirt has given up on outputting tach signal. Connected to the coil and it works again. I chased the wire all the way to the board and it seems ok.


    Wanted to compare the two widebands however didnt have wires soldered to the DB37 connector. With out power at the shop its a little tough to do right now.


    It appears the innovative was 1 point leaner then the AEM so far.


    20171112_135616 by euro2fast4u, on Flickr


    20171112_135605 by euro2fast4u, on Flickr


    So far i wouldnt even spend the money on the innovative, the aem is much more stable


    If the wires and coil remove the miss fire i will schedule for the dyno once again.

    Month later but finally made it to the shop again, new 200 amp panel is installed and approved by the county. now we can run the compressor,welder,heater,blast cabinet all at once

    New and recent engine bay shot.

    20171216_143519 by euro2fast4u, on Flickr

    Its been so long since i worked on the car that i sorta didnt know where to start, so many parts, so little time.

    Decided to look into the fuel system to gauge if the 450 will fit.

    Oem pump
    20171216_154611 by euro2fast4u, on Flickr

    20171216_154614 by euro2fast4u, on Flickr

    New pump
    20171216_154627 by euro2fast4u, on Flickr

    20171216_154645 by euro2fast4u, on Flickr

    Everything looks like it will fit, prior to buttoning up the oem lifter pump and putting everything back i decided to see if the 450 will fit in the tank.

    20171216_154902 by euro2fast4u, on Flickr

    As you can see it is very very tight, i hope i can get it to fit in the tank with some slight modifications

    Started inspect the output fuel line size. I think ill weld a -8 fitting to this and run new lines.

    20171216_155601 by euro2fast4u, on Flickr

    20171216_155613 by euro2fast4u, on Flickr

    3/8" ID is pretty big from my understanding. Should be able to push a large amount of fuel through it. Ill have to investigate some more.

    Now i currently have the oem lift pump going to a walboro 255 and a stock fuel filter, running all stock fuel lines and filter and pressure regulator to 600cc injectors.

    I plan on replacing the oem lift pump with the 450, but do i leave the 255 inline as well?


    Lastly i was able to set up the knock sense input.

    20171216_181452 by euro2fast4u, on Flickr

    I learned after purchasing the controller that knock on the m20 occurs 3-4 after BMEP so unfortunately it will be more of a fail safe setup then anything.

    So small update. Need to yank the engine and regasket the damn thing. to many leaks from last summers oil pan swap.


    https://www.youtube.com/watch?v=C7FE9qw3GkM


    launch control is working , built 20 psi just before this video, this was closer to 10 so loud in the shop


    Happy New Years!

    How long do you guys think it will take to pull an engine and re-seal it and reinstall?

    I also want to fix the Valve cover clearance issue but not sure how to handle that. really dont want to pull the head.

    Its like a very slippery slope

    No offense, but your street tuning AFR's and boost control plots look horrible!
    You really need to improve the wastegate so that it limits boost! Are you sure everything hooked up and sealing well?

    The improved timing and fuel maps look better but it all depends on IAT's, your timing values and your octane!

    I have had good repeatable results with VirtualDyno as have many others. Be sure to enter gear rations, weight, cD, and ambient temp/pressure!






    Data-logging and reviewing the information in the plots is useful (but you have to be detailed enough to spend some time thinking about what data to look at and what it is telling you...

    you are very true on the air fuels. The innovative i had never seemed to work well ever. I recently have replaced it with an aem and i am gettting so much more stable AFR's. Ill have to show a log again.

    So flex fuel sensor came in snagged a great deal on amazon.

    Also been working on the PWM control of the fan and began modifying the GUI.

    Began writing out the code i want for the fan control last night, Ill probably break it up into phases until all parts are incorporated.

    Pulled the engine yesterday. From a running car to engine on the stand 2 hours.

    20180114_160654 by euro2fast4u, on Flickr




    So i noticed a few things and ill have to get a more detailed photos.


    On the clutch, on the ceramic side it appears its only grab on the middle third of the clutch. Kinda strange, calling around today to see if i can get all three parts surfaced.


    Block didnt like the chevy orange


    and i now have a pretty good understanding on why this turd boost creeps. Its gonna get hacked up and fixed while the block is out.


    Took a time lapse of the process, hope to get the videos edited by the end of the week.

    The more i dug into the engine this weekend the more i realized i should have just ran 30 pounds of boost and enjoyed it with zero worry.

    After thinking about it for a day i realized it wasnt that big of a deal. all the ring gaps were excessive, and the engine just seemed well worn out. Ill take the block to the machine shop and get things going this week. I am going to request to be present during the process as i do enjoy it.


    I got the Tiny board to communicate with Megasquirt. Pretty easy once i took a few baby steps.

    well enjoy some cringe worth photos. I am moving shortly less then 20 days and put a crunch on a lot of things.

    I decided to reassemble the engine with all the worn out shit. I am praying it wont knock for a few months while i build a new engine.

    But i am practicing removing all the leaks possible.

    New o ring wire which was amazingly hard to located 0.040 ended up getting some from the craft store. pure copper and .04" amazing.

    20180210_182123 by euro2fast4u, on Flickr

    One thing i wanted to do this winter was to correct the boost creep issues i had. By tieing into both runners and allowing flow to easily exhaust the exhaust.

    20180303_165917 by euro2fast4u, on Flickr

    Mocking up the fan relay and tiny board.

    20180304_151326 by euro2fast4u, on Flickr

    And then at this point i lost communication with the tiny just as i was making good progress.

    2018-03-11_06-23-55 by euro2fast4u, on Flickr


    Thankfully had an extra one of these.

    Looks like i may be able to loop the wg plumbing back to the exhaust to have a nice quiet car again.

    Well engine is back in and starts up and no loud noises. oil pressure is better then before from what i remember

    20180330_134115 by euro2fast4u, on Flickr

    waiting on a bracket to show up to hold the oil return line which i can finish fabricating.

    should be able to button back up and cruise next weekend. curious how the new relocated wg handles the creep.

    All back together, took it for a test drive yesterday and no weird noises. oil pressure seems better. Did not hit boost. I did take it up to 4,000 rpms at 100kpa.

    Moving this week so this is one item off the list. So far see 2-3 oil leaks still, 1 loud rocker, and a power steering leak. o and the shifter is backwards smh.

    sorta amazed i did it hahaha.

    How to turbo your car:
    Step one. Install ecu and learn to tune and or have it tuned.
    Step two. Install injectors and retune.
    Step three. Install turbo parts and bits. get it running with out leaks. DO NOT DRIVE IT. Idling should be ok
    Step four. Retune car
    Step five enjoy

    And back to the car projects. Adding the TinyIOX board to ms2. Going to be adding various sensors such as oil pressure and temp, flex fuel temp and content.

    nothing like working on faux wood floors.

    Bring back so many memories....should have taken a wire wheel to that block to remove all the crumbling red paint! Where do you think the engine leaks are coming from? Seems like the M20 just finds a way to leak.

    Well i drove it for about 100 miles yesterday and beat on it sorta good. up to 8psi-10psi range but tried to stay around 5psi.

    I noticed some oil leaks in the driveway after about 50 miles. When i came back and parked it, i noticed it was leaking from the trans. Everything else on the engine is BONE DRY which is good. I just didnt do the rear main seal and i think thats the cause.

    given that i fixed about 8 different oil leaks and they didnt show back id say im doing well
