Looks like it's time to start tuning all over again using Alpha-N. Bye bye MAP.

I know. It'll have to be changed. This is actually why I posted these images. I wanted feedback.

If that's what it comes down to I will think of something.
"As long as it fits in the OEM casing" I can safely fit a MAP sensor according to the rules. I can't use that sensor because I can't run a vacuum line to it? What good is having the ability to fit...
Here are some pics of the ECU I'm working on making suitable for improved touring. I started with a Megasquirt kit and fit it inside the case of a dead L-Jet.

Any anticipation that the ECU rules will become more lax in the future?
Has anyone been able to accomplish this ECU modification successfully?
The dyno time would certainly take away any doubt that it's set up right. Especially with a wide-band o2. My process for tuning it was not very exacting, but I feel strongly that I have it set...
I have yet to put it on a dyno, but if I see a gain of at least 5hp I'll be happy. I'm going to get some good dyno time in at my friends shop when the weather gets better. I'll have to put the...
After doing some reading I've found that my ECU can make calculations based on the MAP sensor(along with the other, standard sensors) OR it can be set to make calculations based on the Throttle...
I am not doing any competition of any kind at this point. I'm still learning about racing and learning/working with my car; especially since it has been Winter. I probably won't do any competition...
I still have all the original ECU parts so if I ever start doing any actual competition I can revert back to it. I don't know why, but I have a feeling no one is really going to care about my ecu...
Oh, and for anyone who's interested I used a megasquirt EFI controller. Why? It was cheap and a fun project that kept me busy for months on end. I love projects and I learned a TON about EFI...
Thanks, but unfortunately I don't even know for sure if this is going to fly when the car is tech inspected. I wonder if anyone has been able to replace their ECU with aftermarket equipment while...
I have the MAP sensor inside the ecu box and a vacuum hose going to the ecu box.
You know that would be a problem for me since my L-Jet is made from '80s technology and the boards inside take up so much space. I'd enjoy the challenge, though. =)
I'm already making an ECU so it won't be too much a hassle to use all the original wiring and connectors. I just feel bad about cannibalizing the L-Jet circuit board over a measely connector. Oh...
I see. I plan to put new guts into the stock ECU box. I wasn't sure of what else was needed for a legal install of the new ECU. Such as using the stock connectors, but I knew the wiring harness...
If a new ECU were to be installed would you need to adapt the stock engine wiring harness to it?
Thanks to all of you! This all seems to be so much more difficult than I was expecting, but hopefully I can get everything sorted out.
Apart from the rear shocks, some the smaller things that I...
Thanks for all the information! The shocks in question aren't installed on my car.
After getting an idea of all the IT rules from this forum I'm a little freaked out. My car has been gutted of...
Hello. I have a pair of rear shocks that have threaded bodies and I understand that they aren't permitted. However, my car's rear suspension design has the springs seperate from the shocks. The...
Are these rotors ok for ITB? The stock rotors aren't vented, but these are "OEM Replacements" so I wonder if that works.
