Hi ,

I have a Motec m800 on a evo 7 with 6 speed gearbox . not a PnP board
I tune this car with a map and inlet temp.
i use the delco 300kpa map sensor .

What i get is when i drive in the first 5 gears i can go futher then 1.7 bar and even 2 bar boost .
But when i drive in the 6 gear i get errors in the ecu on the MAP and TP sensor when i go higher then 1.7 bar .Also the map sensor dont read higher then 1.7 bar so 270 kpa .


i have checkt the +5v to the map sensor and tps sensor and this is good .

i hope that someone can help me .

thanks ,
Wouter

One question

MAP sensors, Where is it receiving its reference from? Is the line also supplying pressure reference to another part (wastegate, blow off valve, brake booster etc)?

its coming direct from the inlet manifold .

Maybe i did something wrong with wiring .

but i only found one +5v wire on the Motec M800 ( pin A2 )
And when i see the small Delco map sensor wiring its shows for the M8 +5v wire on pin A12 but this is a +8v wiring for the hall sensors .
So i dont used these but strange that this is on the wiring for the delco or would a M8 versie not be the M800 ?

have no one ever have this problem ?

And what would be a good 5 bar map sensor for the Motec ?

Thanks people for the support , i found the problem .
