After fighting for a few months with a weird issue that I could only explain as “stuttering” under boost, I fixed my boost leaks and tested hooking it up to a smoker at my parents shop, changed my fuel filter (which needed changed anyway) and kept second guessing my fixes because the issue just wouldn’t go away. I played with my tune with my MAFT a lot to try to get my AFRs right and finally did after fixing the boost leaks too.
So I found my issue and fixed it – first I’ll start by saying the issue was a stupid one and I don’t know why it took me this long to try this… It was the duty cycle on my LCDBC… It was set to 20, I set it up to 40 while driving down the highway yesterday and the car INSTANTLY woke up and got in to steady boost with no problems finally! Now you would think I should have known to check this between selling my AEM tru boost and installing the LCDBC, but for some reason my brain didn’t make the connection that I did that until yesterday. I didn’t drive the car for about 2 weeks or so between swapping them because I was doing several things to the car at the same time – I figured it got messed up doing something else lol. Just to be clear – this is my fault for not changing the settings, it is nothing bad with the LCDBC. The LCDBC is still one of the best purchases I ever made for my car.
Pretty happy that the car is finally running properly now.
I have 15G turbos on the way finally! Working on getting some bigger injectors in the next couple of weeks. I got a Walbro 255 and hotwire kit from Ninja last week that I plan on installing when I install the injectors.
I decided to hold off on going E85, I plan to do it still but I think I am going to upgrade down the road a little ways when I can afford it. For now, I’m still in the process of building my 4 bolt block with forged internals and that will be the last big purchase for awhile.
Progress feels good and it feels really good getting in the car and driving it without saying “WHY IS IT DOING THAT?!” lol.
More progress today also!
On my lunch at work, I had nothing to do so I rigged up an OBD1 to OBD2 adapter to see if I could get my LCDBC communicating with my ECU and guess what!! I GOT IT! The adapter that came with my Chrome ECU apparently wasn’t able to make a good connection with the LCDBC. Now I can finally take full advantage of this awesome product!
Really excited that things are starting to fall in place finally.
