Any one running a 4 bar map..been lookin into it to and havent seen anyone talk about it so just wonder if anyone is running one and tuned on one..does it read correctly on psi with the lap top...thanks

 

I have one that doesent read right. and I know of one other one that dident work.

Maybe we got a bad batch?

 

ive gotten a bad one from one from a seller on here and they sent me a new one no questions asked ive been driving on it for a few months i guess now it reads right and alot better then my gauge

 

We have tuned several cars on them without any issues.

500+ whp car that has been running one for over 6 months:

That is weird considering they are all tested before being shipped from what I have been told.

 

using a hondata/ omni 4bar here without issues thus far for some months.

 

I didnt know anthony had one

 

i have one, no issues. make sure the voltage pressure conversion is correct.

 

What is it? I am willing to try it agian. is it the same as the "omni power 4 bar" in the map options?

 

ya like on crome pro they dont have hondata just have a zenocron 4 bar do you click on that or just go to custom map sensor

 

Based on how many 3rd party companies supposedly make the GM 3bar, you're still better off with the Hondata/Omni 4bar. You can see any questionable sensors are replaced w/o any stress. Try to explain to the parts counter guys why you think your GM sensor doesn't read low vac or high boost all that well. They'll either laugh at you, or charge a 30% restocking fee.

 

They have worked out great for me. I've tuned many setups with them and havent had any issues. They also seem to be fairly accurate in comparison to our dyno map sensor.

 

good info, i was wondering this myself

 

im at work right now I will get back to you when i can pull it up on my laptop

 

i had one but they don't work with s200 lol

 

actually it does work from what I understand, you just have to use romeditor4 instead of the previous romeditor3. romeditor4 had custom map sensor support added so you can configure for a multitude of previously not supported sensors.

until I upgraded to the s300, I had originally debated using the new version/ s200 temp. never had to though.

 

I've had one on my car since they came out. I have not had an issue. I've seen as much as 37psi on the logs and the car make ~800whp.

 

o rlly??? hmmm wish i would have known this. I was told it doesn't work with s200 so i'm just rockin old trusty 3 bar. Thanks for the info though!

 

Im bringing this back fomr the dead for the simple fact that Im not getting the help I need from Hondata. My 4 bar DOES NOT read correct boost and Im sure all the people that's having this issue are not crazy. When I hit 9lbs the hondata 4 bar only reads 4 to 5 lbs of boost in the hondata S300. I had NO issues with the GM 3bar I was using. My car went from 11.5 AFRs from 1lb of boost to 17AFRs at 9lbs of boost. Iv'e tried tuning and tuning with no positive results. I know what someone will say, "you need to tune your car!" I was running over 20lbs of boost on the GM 3bar no problem self tuned. Also, I datalogged with the S300 and with my zeitronix software with the MAP sensor voltage readout. As the boost rises on the Zeitronix readout, the MAP sensor voltage fails to rise and it just sits at 1.39Volts. The vaccuum reads perfect, but it's just something about the boost area that's not reading right. Does anyone have any suggestions? Also I was wondering if Omni tests their MAP sensors on boosted vehicles also? Im looking for any help I can get. Thanks!

 

I have the Hondata 4bar on my car, and it is working perfectly at 30+ psi.. I've used them on numerous cars that I've had on the dyno with no problems, and the readings match that of the dyno pressure sensor.. Have you considered sending it in for testing?

 

I think that's what I will have to do. but then they probably might charge me for that. I would have hoped that after spending all that money on a MAP sensor, it should have came working. But Im wondering why are other people having the same exact issue? I could have understand if the issues were different, but it's the same exact symptom.

 

ok i have to retract my statement. My 4bar took a **** on me a few weeks back mine was reading 44psi at idle and of course would not start the car. I just wanted to give him hell....lol

I talked with Omniman and there a few batches out that have bad silicone on them. funny this was bumped I will have him explain what was explained to me.

 

i guess the bad batch are still around my 2nd one has been working great since oct . off topi turbo are you running.

 

i dont have a boost gauge anymore and i run 18psi ish and i've been running 15.7-16.7 not sure if im actually at 18-19. I cant find a boost leak anywhere. If it's wrong it will find out when i get retuned

 

Since the Hondata map works so well in the stock location, would I have a problem running my GM 3bar using the that same vac source on the throttle body?
