Mike B Posted October 27, 2008 Share Posted October 27, 2008 (edited) Hi Everyone, been a while since I have been on the board, but I've had some time off and have devoted 3 days to the supra in the attempt to get all the niggles sorted. FBW First on the menu was the FBW throttle. I know of few that keep the fbw, but I like the det protection so I have persevered. The problem is that when in single tune the ecu decides to retard the throttle occasionally, half of the time it will not give full power in 2nd gear, and 3rd gear sees throttle ghosts from time to time. There are a number of things this could cause it, and I have now come to the end of my diagnostic trail, unless you have any suggestions; Not det related; seperate det monitor shows nothing Not MAF related - put a variable resistor on the feed, turned it down to nothing (on the stock ecu's feed - downstream of the fuel ecu before you blow a bloodvessel!) Not MAP related, again variable resistor downstream (as above) no effect. So what could it be.. (my original mapper said it could be the above) There are a load of sequential signal feeds, but... what other diagnostic signal feeds could cause troubled readings to the ecu, enough to cause it to shut throttle on a single car?? any ideas? APEXI BOOST SENSOR The other stumbling block today was fitting of the said apexi boost sensor. Square plug, round hole... new sensor does not fit the old connector, so what goes where?? one pin is marked with a bulls eye (circle with dot) one is marked with a G one is marked with a V colours of corresponding plug wires are red, yellow and black. Now I could take an educated guess at this, but feel free to guess as well, see if we can get a concencus! Mousey Opened the bonnet this morning and what should be sat square in the middle of the cam cover but a field mouse. I looked at it thinking "I really want it to run out of the car" and it looked at me thinking "I really want to run and hide in the car" Last pick is of it staring at me from inside the wing. didn't get it so there is a mousetrap in there tonight! Tomorrow is boot rubbers, front wing fitment, passenger hub replacement, brake caliper cleaning. regards to one and all Edited October 27, 2008 by Mike B (see edit history) Quote Link to comment Share on other sites More sharing options...
merckx Posted October 27, 2008 Share Posted October 27, 2008 Last pick is of it staring at me from inside the wing. didn't get it so there is a mousetrap in there tonight! A humane mouse trap? They're only £3 and they don't hurt the mouse, you can release it elsewhere. Quote Link to comment Share on other sites More sharing options...

If you can fix my throttle ghost and get the right wires/connectors i WILL swap it for a humane one... lol I only use humane ones, although you have to check them every day, otherwise it's not so humane!

Wez Posted October 27, 2008 Share Posted October 27, 2008 Have you listened to the engine with det cans? What det monitor you using as they have to be setup for the engine to give a true reading? Quote Link to comment Share on other sites More sharing options...
