I just installed my EMS over the weekend and got the car to idle. It idles horably but I know I need to get it to a dyno to get it tuned. My questions be for I get that far are:
1: How do you wire in the 3 bar MAP sensor? Do you just cut the factory wiring and splice this in.

2: The car is a 99" accord 4cyl. I switched out the 240cc injectors to percision 780cc injectors. How do I scale these down? I'm switching from the greddy e-manage and it had a conversion table, but I can't find it on the EMS.
I would just like to get the car to idle a little better so I can drive it on the trailor and the be able to drive it onto the dyno. No street driving till it gets tuned.

If it helps, the set up is: percision SC52 turbo, percision 780cc inj, crane ignition, HKS EVC boost controler, Tial wastegate, JohnnyRaceCar 8" intercooler, 3" down pipe, High flow cat, Greddy exhaust, CP pistons, Crower rods, L.A. sleeves, and Manley valves. Any help would be greatly appriciated. I've checked the AEM forums and had no luck. Thanks in advance.

 

I strongly suggest you get that car tuned professionally! or by someone who knows the software, dialing fuel back is easy simply drag over the region and lower the values..... but since it seems to me you have no idea about using the software i'd definatly suggest not driving at all until it was tuned...... hell i'd even tow it to where the tuner is located..

Go to hondata's website, they have a 3bar wiring guide, yes u can just cut the factory or splice it... since ure OBDII i sugguest this, so u can go back to stock ecu/injectors for inspection purposes.....then in the AEM software, u need to switch ure sensor input to a GM 3bar...

 

Thanks, that answers the question about the MAP sensor. I plan on having it towed. I have to go to cinncinati to get it tuned. There's no way in hell I'm driving there from Columbus with out it being tuned. I just need to be able to get it on a trailor to get it down there.

 

Need some help with the EMS...Give me a call Id be glad to help you out.
513-870-0999 Ask for Rick, I work @ a tuner shop in Cincinnati, AEM factory trained also.

 

Quick question...

Whats the highest boost you can run with the EMS and GM 3 bar.

Sorry for the OT!
Thanks!

 

As long as the rest of your set up is built for it, the GM 3 bar allows you to scale voltage up to 30psi.

 

Cool. Just wondering since the max with hondata is 28.

 

Thats the limitation of the sensor.
Its actually 28ish psi.

 

Thanks tuned1 I was thinking of bringing it to you guys to have it tuned. I have a friend that lives in cinnci and is going to set up the suspention after it gets tuned. I'll try and give ya a call later.

 

Hope to be hearing from you

 

it depends on teh sensor... there are actually 3 different gm 3 bar maps...

the gm 12223861 will read from -14.4psi to 31.1 psi
the 12219935 will read from -8.3psi to 30.8 psi
the 16040749 reads from -13.1psi to 29.3psi
