Default 4 bar map sensor

Why does the omnis start with 04? Would I be able to use those at all on my bug eye or would I settle with the Perrin? Also if I'm not going over 23 psi do I need one for speed density. Il be around 20-21 psi on a 18g but I did the hybrid and 1000cc injectors. The car is fully modded

There have been reported problems using them on the 16-bit ECUs. Search for it and you will find it. I know it will fit but the ECU doesn't always like them. Run the AEM or Perrin if you need a new MAP sensor.

Ask your tuner first. When I went Speed Density my tuner requested that I buy the OMNI 4 bar specifically.

It communicates fine, but you can't do a negative value in our ECU so you occasionally get a high idle. Luckily, my tuner was the guy who created the Carberry Speed Density ROM, so he had a new revision that did allow for a negative value.

Omnis dont work well with dbw cars. 02-05 wrx.

But if you go with a carberry tune ot will work out just fine.

Otherwise do with an Aem map sensor
