ive been having issues with my check engine light coming on and off iam almost positive its the map sencor , i read about ppl with map sencor issues and they seem to be on dott with what iam going thru wich is not being able to rev over 3k rpm and bogging out. Weird thing is sometimes check engine light wont come on and car runs Perfect! anyways

i came across these 2 wires? iam not sure what they are , if any1 can help identify these id appreciate it. thanks!

 

 

Map and iacv it appears. Check your codes first.

 

iam on hondata s300 i tryd hooking up the laptop to it and nothing shows up
i have itbs so its hard to see where these go to

 

Bumpppp

 

Do you have a map sensor or an IAC valve hooked up to your ITBs? If you don't, then these connectors probably don't go anywhere.

The connector with the 3 wires, YEL/RED, GRN/WHT & WHT is for the MAP sensor. It's hard to see how many wires and what colours they are on the other connector. If I had to guess I would say EACV (IACV)

If you can't rev your engine past 3000rpm. How do you consider that your car runs perfect. sounds kind of like it's in limp mode??????

What method are you using to tune the ITBs? I'm going to guess Alpha N or mass air flow - Without the MAP your obviously not using speed density.

 

okay thats whats weird. on Rare ocations the Green Light on the hondata comes on and NO check engine light , when this happens the Car runs PERFECT Now... when the red light on the hondata comes on the check engine light also comes on which makes the car run like ****. their for not letting me go over 3k rpm and bogging out.
what exactly is limp mode?? and the shop that hookd it up didnt really tune it . what he did was hook it up to the computer and basically did a " street tune " ? just basically got it to run with the itbs ..sorry for the life story haha hope u can help Ghost!!

Limp home mode is when the ECU reverts to a default set of limited fuel and ignition maps. These maps will only allow the vehicle to operate under a preset RPM (3000-3500). It happens when it is missing signals from key sensors. The MAP sensor being one of them. The ECU will only give you enough to get you home/to a garage/or to a tuner to have the problem diagnosed and fixed.

If you have not properly tuned your Hondata, I suggest that is something that you should look into.

 

Oh ok that makes sence ill go ahead and do that
thanks again ghosT!
