Could someone please walk me through making the changes to the settings on the Utec Map Sensor I finally recieved today?? I thought it would just be plug-n-play...

Surely someone on this board has installed the Utec Map Sensor and had to make these changes in order for this to work correctly???

 

I would like to know more about this too. Subscribing...

it is plug-n-play.

You shouldn't have to change the pre-entered values of gradient and intercept in the UTEC. Make sure you have the other UTEC settings correct...such as the setting for absolute or gauge pressure.

Read the manual (many times); it tells you everything you need to know!

 

Looks like I will have to contact turbo xs tomorrow for more info. Funny thing is after 2000rpm's the car is falling on it's face hesitating badley.. I will keep the rest of you informed of my findings...

If you loaded the base map "parameters" files from the TXS website, then it should be plug and play. The tune is going to need some tweaking to get everything running perfectly.

It should be plug and play...but I am having the same problem. Any hard throttle or over 2500 rpms it just "falls on its face". I was planning on playing with my fuel pressure regulator again this weekend, but I'm not very optomistic. I have tried 3 different sets of parameters, and changing the fuel maps in many different ways.

 

Probably just needs to be tuned. The basemaps are just rough starting points.

 

That's what I'm hoping. I was just trying to not have to tow it, so it could be tunned.

 

do you have any logs to post? that'll help if you want an online diagnosis.

 

Ok guys after speaking with Turbo xs it appears I have an older version Map Sensor that Will Not Work with the 350z..... That being said they are shipping one out to me asap.. What a Great Company to deal with...

well, I guess that solves it!

 

I hope so but I will have this part tomorrow and will follow up with a post....

Well sorry to say but the new map sensor I received today is not the fix I was looking for... It is the right map sensor but my car is still runing way rich for some reason.. At idle it is around 7.5 to 8 a/f.... I'm starting to think those used injectors I bought might be problematic..?? After spending countless hours checking and rechecking things I do not know what else to do...
