I got a AEM EMS 30-1313. I'm running a 5 bar map sensor and a stock TPS on a 75mm Boomba TB.

The issue is the engine load is raising when I hit the throttle. For instance at 10% throttle I so 0 psi and at 20% throttle it shows around 10 psi. And the car is off! Help!

Ideas?

So far I have checked the wires up to where they coverge over the trans, under the battery. And I sent the ECU to AEM and they said it checked out. And I replaced both sensors.

Please let me know if you can think of anything


Thanks,
Aaron

Give us a data log. Also datalog your TPS volts. Your car might be going into TPS failsafe mode because it is outside the TPS Range.

What does your TPS read at idle. It should be about ~1.5% at idle and about ~98% at WOT.

I will get a log on here tomorrow morning. Can you describe what tps safe mode is?

sure

TPS to Load is the table under breakpoints template

In the event that you get a bad TPS signal you car will go into failsafe mode. So it will say at x tps you are at x boost. I am sure that works for your pressure sensor also. I am not 100% familiar with what the table does 100% but you could start there.

When I was tuning my STI on S2 AEM I did not setup my TPS correctly and that woudl kick me into TPS Failsafe mode which used that table.

How can you tell if you are in failsafe mode? And could a crossed wire or something in the tps wiring send it into that?

I just went looking through the manual. That failsafe mode describes my problem exactly. Do you know which pin on the 30-1313 is the 0 to 5volt pin for the map sensor?
