I know that way down the road, but I haven't been able to find anyone that can tune these cars. The project looks great though. It's making me want to give it a go 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! Edited September 23, 2019 by LittleBlue! Link to post Share on other sites
LittleBlue! 102 Posted September 28, 2019 Author Share Posted September 28, 2019 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. Shinobi777 1 Link to post Share on other sites
LittleBlue! 102 Posted September 29, 2019 Author Share Posted September 29, 2019 (edited) 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 Edited September 29, 2019 by LittleBlue! Shinobi777 1 Link to post Share on other sites
LittleBlue! 102 Posted September 29, 2019 Author Share Posted September 29, 2019 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. Link to post Share on other sites
LittleBlue! 102 Posted October 1, 2019 Author Share Posted October 1, 2019 (edited) Here is a snapshot from yesterday's log. I hit just over 4 psi at around 4,500 rpm. My torque table was limiting me as the engine was creating more torque than the stock table was requesting (go figure :/). So I adjusted my fueling to account for the additional air and added 10 percent to the higher end of my torque tables. Hopefully, I see higher rpms tomorrow (I was limited to around 4,500) and higher boost. Edited October 1, 2019 by LittleBlue! Shinobi777 1 Link to post Share on other sites
LittleBlue! 102 Posted October 1, 2019 Author Share Posted October 1, 2019 Got up early and took the car out before heading to work to make sure the car ran good for a daily commute. Seems the changes I made helped but I'm 85% sure I've maxed out my MAP sensor. Hopefully, I'll order one at work today. I think I want a 2 bar because I will never exceed that and the resolution will be better than a 3 bar because it would have a smaller VVE table. Until then, my boost reading tips out at 4.21. Unfortunately, my mechanical boost gauge seems to be less than reliable so I may have to tinker with that or replace it here soon. Link to post Share on other sites

Summit Racing sells the GM 3 bar sensors. I ordered this sensor this morning. I was hoping for a 2 bar option but this is OEM and looks like a direct fit, not to mention the price was right. I ended up splurging a bit on delivery but there is a live tuning session on goat rope garage on Thursday so if I have questions I can ask then. Otherwise, I can send tunes in via email and I will be scheduling another session for October. thismarks and Shinobi777 2 Link to post Share on other sites
LittleBlue! 102 Posted October 11, 2019 Author Share Posted October 11, 2019 Engine bay ramble while I address an oil leak in the oil return line and prepare for my next tuning session on Saturday. I am now running the 3 bar map sensor and finally hitting 6,000 rpm. Currently seeing about 5psi of boost. thismarks 1 Link to post Share on other sites

LittleBlue! 102 Posted October 15, 2019 Author Share Posted October 15, 2019 I had my second tuning session with Goat Rope Garage on Saturday. We adjusted my torque tables, driver demand table, and the variable camshaft tables. The car is running like a top. The two areas that I would like to improve are low rpm range acceleration (driver demand table) and power enrichment. I have a cvt transmission, so I know I will be somewhat limited on the low rpm acceleration. Long story short, I'm hitting 5 psi of boost and 6k+rpm and the little car sounds like a whistling monster. Couldn't be happier with the progress thismarks 1 Link to post Share on other sites
LittleBlue! 102 Posted October 19, 2019 Author Share Posted October 19, 2019 I have another tuning session tomorrow. I decided to break up this month's hour and I've only used about 20 minutes this month. Tomorrow I plan to focus on torque based tuning. The modifications made to my car has changed the fueling and torque. In order to determine how much I need to modify the torque tables I need to log how much torque the engine is actually making compared to what is being requested. I'm setting up a histogram that logs engine torque on a chart with the x axis being rpm and the y axis being cylinder airmass. Tomorrow I will log the engine torque and look at how far of the current tune tables are. I will start putting together some videos showing the process to help better explain this but these tables and the fueling tables are really key with these newer torque based ecus.

LittleBlue! 102 Posted October 23, 2019 Author Share Posted October 23, 2019 As I have been tweaking my torque tables, my boost has been slowly climbing. No crazy increase in boost but I am officially over 5psi and the car is getting faster everyday. Link to post Share on other sites
thismarks 65 Posted October 23, 2019 Share Posted October 23, 2019 Really wish I had the time to buy and tune the HP tuners pro kit. Maybe in the future. Love seeing the progress updates! I've come a long way but, I feel there is still a long way to go. It's nice to be able to see someone else get their project to work and have some original information. I am starting to feel how much work you put into your project and respect it. I really hope you get some decent numbers when everything is running perfect. Can we get make some guesses? 135-140hp to the wheels would be my guess at 8psi. That would make the car fun and honestly I believe it should have came that way!

That would make the car fun and honestly I believe it should have came that way! It has bee. A long journey. Some of my modifications were unnecessary but I used this project as a learning process so I guess mission accomplished on that front. I was always hoping for over 100 as a minimum hp and my fantasy was to double the 84 horses mine came with stock. I always thought I would do a dyno and I still might but I'm thinking that money can go into my next project this winter There is a calculation for horsepower in hp tuners that I can add to my logs. No clue if it is anywhere near actual or what it is based on but I'll add the channel and log it tomorrow just for fun. It's been fun watching your project. You are cruising along. Don't let the bumps get you down' you will just know that much more when you are done. I hit a lot of snags but I think the lessons were well worth it. My favorite part is I get more looks when my spark spools up than I ever do driving around in my s2000 haha Link to post Share on other sites
LittleBlue! 102 Posted November 11, 2019 Author Share Posted November 11, 2019 I had few people ask about the exhaust. I have been meaning to work on the mounts and vide the entire exhaust while under the car but I have been working on a lot of other projects. I did come across this picture of my homemade mid pipe. The welds are ugly but it works great thismarks 1 Link to post Share on other sites
thismarks 65 Posted November 11, 2019 Share Posted November 11, 2019 I am actually really glad you posted this. I'm sure my welds are going to leave something to be desired... I picked up a cheap 140amp DC inverter welder and haven't started welding as I ran into a space issue with my coolant fittings. I'm going to end up with lots of spare turbo pipes, connectors, and fittings. All in the learning process. I'm looking forward to seeing a shot of the whole exhaust if you get a chance.

LittleBlue! 102 Posted November 14, 2019 Author Share Posted November 14, 2019 Pardon my 1 unrelated post but I just got the first few parts for my next project. I'm putting a gt45 on my v8 4.7 Jeep commander. I would have never thought to try this if I didn't learn by tinkering on my turbo spark project. The size difference is insane. On a related note. This means the spark needs to be reliable on e85 during the MN winter as it will be my daily driver. I have some tuning to do on the cold start side of the equation. thismarks 1 Link to post Share on other sites
LittleBlue! 102 Posted November 29, 2019 Author Share Posted November 29, 2019 (edited) Well, something has gone catastrophically wrong as I was out and about today. I made it back but it had leaked a good amount of what I'm 99% sure was oil. Also, I thought it smelt/felt like I was burning the cvt belt but I'm not sure if it is just a belt and that is plausible or it is a chain. Either way, it no longer engages. I did get it to spin the tires on the ice in the driveway when I started it up a few hours later to move it. Luckily, it was in the driveway but that's where it sits. Now, I'm either going to replace the belt, do a manual swap, or look to a complete drivetrain swap or scrap it and save it for the project after the Jeep. Edited November 30, 2019 by LittleBlue!

thismarks 65 Posted November 30, 2019 Share Posted November 30, 2019 Imo, I'd look into the manual swap. It makes the car perform much different and they can be had for a reasonable price from a salvage yard or even eBay. I'm still wondering when 5th gear will be useful as a power gear, but being able to demand the power when needed is so much better. Sad to hear the problems your facing, but I have been there. Here are a couple of links: Manual and CVT /Auto LittleBlue! 1 Link to post Share on other sites

Erisafirehawk 0 Posted January 29, 2020 Share Posted January 29, 2020 I'm looking at doing something similar this year (I hope). What injectors did you use? Link to post Share on other sites
LittleBlue! 102 Posted April 27, 2020 Author Share Posted April 27, 2020 I took out the existing turbo related parts. Going back to NA to work out the CVT issues and then put a universal turbo on. Removed the turbo and intercooler today and added my temporary cold air intake. Link to post Share on other sites

Are you still looking to do this? Yes. But insted of turbo, I'm thinking a small supercharger. There's twin screw ones they use on old vw 1600 engines that I think would work well. Also, mine is a manual, so I should have the issue with the trans that you did. Link to post Share on other sites
