That's a pretty large margin of error. Smile

It's not an error issue but temperature. The official datasheet shows that.

I see. What's the "normal" value before temperature intervenes?

Couple more for you...

motorola
mpxh6300
scalar 616.59
offset 10.95

mpxh6400
scalar 826
offset 34.78

Please double check as it has been a long time since I worked it out/used.

Just found the datasheets on these motorolas. That's pretty close, but may need just a touchup. Thank you.

It's probably the same as the Omnipower listed above.

It is. Spunkster from Hondata has been using it for a while now I guess. He notes that here.

My omni Power 4 bar is getting delivered today. I'm switching out for the GM 3 bar posted by pentaq. I have talked to a few tuners and I was going to get the AEM 3.5 bar but most noted they didn't like it. They steered me towards the Omni saying it works great....so i bought it. Very Happy

The AEM works well, but there's nothing like a true plug and play 4 bar. Smile
