My LCD screen project, boost, WBO2, Knock, etc

Autozone and Oreilly's can't check ODBI, I just went the other day and neither had the plugs to do it, so I'll have to go to a dealer and see.

Someone asked for improved turbo spool up so I created "PSI start" and "PSI end". Let's assume 50% duty cycle gives us 15psi and this is our desired boost level. Anything above the 50% duty cycle line will improve the turbo spoolup. In the ideal world we would switch from 100% duty cycle to 50% duty cycle when we reached 15psi, but of course in the real world wastegates can't react that fast and would cause a major boost spike. Instead what we need to do is ramp down to our desired boost level to avoid a boost spike, this way we can enjoy the improved turbo spoolup without any side effects.



On my car I experience some boost loss at high rpms -- probably because I'm still using a stock catback. Here's my settings for compensating the loss:

Duty Cycle OFFSET:
4000 +0
4500 +0.6
5000 +1.3
5500 +2.0
6000 +2.6
6500 +3.3
7000 +4.0
7500 +4.0
8000 +4.0

I currently don't have a CEL light at the moment, I'm waiting for it to return before I can test for it again.

Hey just an update. I used the stock wiring... works great. And there is two less new wires in the engine bay. the ECS button conversion for "push for boost" works great. I love this thing!

Do you have your emission stuff all hooked up? Ie: EGR and Evap?

Yes I do, but I don't have the 3rd and 4th O2 sensors so I should be getting a CEL for that. The old Mitsu error chart doesn't have a code for those extra O2 sensors because it only lists 16 possible faults, so I'm assuming the CEL can only be read through OBD2.

I just went to the mitsu dealer to have my code checked and spend $86 to learn that it was a front o2 sensor code, which I had suspected seeing how it's cut. So this is definitely something the unit should have read, but it couldn't for some reason.

Looks like I'm late to the party, but this is one of the coolest things I've ever seen. Nice work!

AEM Compatibility please.

That's strange seeing how you have OBD1 as I was able to pull codes on my 93 RT/TT when I tested it -- I'll look into it further.

I have a weird issue with mine. Anytime I go wot it turns off and reboots almost at a certain throttle position. Even if I'm in 6th gear and mash it at 30mph it still does it. I have litteraly checked everything with no faults found. Another is when I go to read or delete codes it freezes until I reboot it. I have a 94 hybrid
