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

Is the issue with the DBW 02-05 WRX and OmniPower MAP sensors the high/irratic idle issue? Is this something that can be over come with OpenECU tuning?

I am looking at either a GM/OmniPower/Perrin MAP sensor upgrade and want the least amount of headaches aka best bang for buck. I've located a Perrin 4 bar MAP sensor for $60 and the guy told me it will be plug and play into my stock harness and will run fine in my 2002 WRX. Can anyone chime in on this?

I just realized that the Perrin MAP sensor is the same as the OmniPower MAP sensor. Looks like my only choice really is the GM 3bar or AEM.

Your only option for speed density is AEM 3.5 or 5 bar for that year. I'm doing the speed density conversion + carberry on my Bugeye currently. I bought this to make it easier on me (Didnt feel like splicing the MAF wires to hookup the IAT). I know I could could of saved like 60 bucks or w/e by buying everything separate but there is something is to be said about plug and play setups. The AVCS wiring harness from IA Performance was the same way. Sure you can DIY for cheaper but a system with wrapped wiring harness is pretty nice

That plug and play kit looks nice and all but can't I just buy a $50 GM 3bar MAP sensor and use the stock IAT sensor from the MAF?
