    This is awesome!

    For exhaust, I would consider a full exhaust, either doing it yourself or having it done for you at a muffler shop unless you can find a direct fit aftermarket set up. Best upgrade while maintaining street legal status would be larger exhaust diameter and high flow catalytic converters. You would probably throw a check engine light without a tune but I would recommend licensing under HP tuners anyways. If you are looking for performance from exhaust you will need to adjust the tune anways IMO. This may not be true for a small range of improvement You could look at slig

    So I took the car out first thing this morning after adding the wastegate bracket and I'm making about 4psi of boost. The car is so much faster now that the wastegate issue seems to be addressed. The turbo noise is also like x10 what it was recently so I'm not mad about that either. I need to rework my fueling for the additional air but I will post a video later.

    During the tuning session today it was confirmed my wastegate was likely leaking. This was an issue because I had to clock the turbo to fit in my car and when I did, the internal wastegate mounting bracket on the turbo no longer lined up. I finally made a bracket to securely mount the wastegate. Hopefully tomorrow I will see higher boost

    I just finished my first one hour session. Super informative. You can log above 1 bar with a 2 or 3 bar map sensor and the operating system can be adjusted no problem. I think 1 bar should read a little bit into low boost. I need to work on my wastegate a bit to build any significant boost. Currently, just barely registering boost but I know what the issue is.

    Hey Edward, I'm not going to be able to solve your problem but I might be able to help. If your brake is having issues, you will probably want to check the cable tension and the brake pad. If it is the tension on the cable, you will probably need to pull up the boot around the handle that you pull and turn a nut to increase tension. If that is tight I would look at the pad. You should consider including more information on your vehicle year and explain what is wrong with the e brake.

    Updates, we are calling in the experts, Goat Rope Garage. Kyle has a YouTube channel full of I formation on these GM style ECU and I have signed up for a one on one course for this month and likely October. My main focus will be: tuning VVE tables, tuning MAF, and timing. I will also ask about sensor and ECU capabilities for boost, and hopefully get the bugs in my flex sensor worked out. I plan on updating this entire thread with new information when I am done. If you are interested in tuning your spark you should check the channel out!

    Nse1255, if you are still interested in tuning, I am having Goat Rope Garage from YouTube help me tune my car. They offer a $15 a month option where you can send your files in for tips and tuning. I'm doing the $75 option for 1 on one this month and probably October. Hopefully. I should also know these ECU fairly well when I'm done and would be happy to help!

    Looks badass man!

    I'm going to ask about this during my tuning session. The sonic and cruze have the same ecu and turbo so I think I may be misinformed on what is possible. Maybe the stock setup is sufficient or I can add the MAP sensor you mention. To be continued.

    Prelude owner to Chevy spark owner: "Is that thing turbo'd?" I got a kick out of this encounter while I was data logging today.

    While reading the HP tuners forum I came across a reference to a YouTube channel, Goat Rope Garage. I've watched a few videos that have been incredibly helpful and relevant for the 2014 Chevy spark ecu. Today, the host of the show announced an option for an hour session of one on one tuning for $75. I signed up today. You also get access to videos and can send files to have him review and provide feedback on throughout the month. Another great deal is $15 a month, you don't get the 1 on 1 hour session but you can watch the videos and send in your files as well. He al

    I have been tinkering with my idle for reasons that aren't relevant to your situation but the troubleshooting should translate. Your issue is either related to air, fuel,spark, or some combination of those. Air I would consider cleaning your mass air flow sensor and replace the intake filter if it hasn't been recently. Fuel Sounds like everything is stock for the fuel system so I would assume if it is fuel related it is either injector or O2 sensor related. If you don't have a check engine light, I wouldn't suspect an O2 sensor issue but I wouldn't rule it out. For

    Looks like there are options. I do not own the same year but did a quick search. There seem to be various options depending on what you want here is an example of a kayak rack for a 19 spark https://www.carid.com/2019-chevy-spark-roof-racks/yakima-bowdown-kayak-rack-1546517931.html Full disclosure, I did a brief search so make sure you are comfortable with installation requirements and fit but I think there are good options out there

    For what it is worth - In my 2014 the ecu has the electronic governor set to 109mph stock. It can be raised with hp tuners. I maxed it out tosomething over 300mph (essentially removing the limitation) but I have not seen how fast I can get it since. I've done a similar change in my Jeep and confirmed the govenor was removed.

    I finally fixed the last oil leak this morning. I kept thinking the issue was where the hose met the fitting but all I had to do was tighten the fitting on the other end a bit. A bit hard to reach with a wrench so I'm assuming that was a contibuting factor. Super happy it was an easy fix and I was just lazy and not really tackling the issue until now.

    Everything seems mechanically sound as of now, I intend to push it as I start to dial it in. I had not thought about raising rpm on my spark yet but I did raise the rpm on my Jeep with HP tuners. I can post a stock spark file and HP tuners editor is free software so if you are interested you can see what parameters are able to be changed and what the stock settings are. I'll look into the rpm limit today. It was easy to change on my older Jeep but the newer GM stuff is notoriously complicated.

    I've been dialing it in while driving to work. I log the data as I drive and then it's really just a copy paste change using the data logged. Unfortunately, I have a small oil leak from the oil feed to the turbo that I need to address before driving it to work again. Most of the changes I'm making are in the VVE table virtual volumetric efficiency. I have that table pretty good up to about 4k rpm. I'm excited to see how it runs when it is good up to 6k. My Spark has the CVT so it should hold rpm and boost at 6k if I can iron everything out.

    Not totally relevant to your removal question but when you do get them removed you can also consider hydro dipping them. You would be surprised at how many local places might do this for a reasonable price. I'm looking to have the stock"wood" trim pieces done in my Jeep either stainless look or carbon fiber but I too need to learn how they are removed.

    Cool idea with the push style fan set up. I'm looking into that for some extra space.
  22. LittleBlue!
    Room was definitely an issue for me as well, I had to get an aftermarket radiator fan to create some space for my set up. True confession I removed the AC compressor and lines too. It's not ideal for a daily but I don't regret it too much. Windows down and turbo spool works for me Right now, I need to address a small oil leak where I tried the turbo oil feed in. I like the oil filter adapter you ordered so I might have to explore that or another T fitting. Once that's addressed I will be back to daily driving, logging, and tuning. Best of luck on your project, I'm excited to watc

    I finally ran the wideband wire and boost gauge vacuum line through the firewall. I like the placement of the gauges and do not miss the loose wires.
  24. LittleBlue!
    I installed a T-fitting in the intake manifold (white plastic T in picture) to hook up as my vacuum line for the blow off valve and my boost gauge so I know what the pressure is in the intake manifold. Unfortunately, this manifold absolute pressure sensor is not set up to read above atmospheric pressure and the ecu (e78) does not appear able to monitor above 1 bar (atmospheric pressure) This is not an end all issue but it does make tuning for boost a bit of a challenge (especially for a newbie like me) On a positive note, I hooked my boost gauge up and confirmed I am making boost.

    Day 2 of driving the turbo spark to work. I put in a new tune and filled up on e85 before heading out. Still seeing backfires at about 4200 rpm but it is getting better. I had a video but removed due to error on my end. Better videos to come.
