Steve Posted October 6, 2006 Author Share Posted October 6, 2006 Alex, Havent got the old injectors anymore. Have tried a different Emanage unit and a stock ECU. Can i just unplug the RLTC box just to prove that this isnt doing something weird? Quote Link to comment Share on other sites More sharing options...

I'd see if you can borrow some 440cc injectors and test with them in. Quote Link to comment Share on other sites More sharing options...

absz Posted October 6, 2006 Share Posted October 6, 2006 did't read all your posts so it might have been covered but i had a similar problem with my afr's reading low at times, and i managed to trace it to a bad connection on the fuel pump connector block in the boot might be worth checking. normally with bad connections the wires tend to slightly discolour and are brittle due to heat build up which you can look for, also leave engine running when checking wiring and connecters to see if you hear a change in engine sound.

Steve Posted October 9, 2006 Author Share Posted October 9, 2006 The car is now throwing up a fault code of 31. According to the manual it is something to do with the Air Flow sensor circuit. But mine is a Jap car and doesnt have a Air Flow meter. So what can cause this fault? Quote Link to comment Share on other sites More sharing options...

Alex Posted October 9, 2006 Share Posted October 9, 2006 AFM code = MAP code on a J-spec. (I believe). I'd swap the sensor and re test. Quote Link to comment Share on other sites More sharing options...
Sheefa Posted October 9, 2006 Share Posted October 9, 2006 Homer - thanks for watching the vid mate and providing your comments. Much appreciated. I wasn't sure if my AFRs should be swinging like that at low revs i.e. below 4,000rpm. That's kind of good news I suppose although I don't know if the problem persists above the 4k mark when the 2nd Tubbie comes in! All I know is it's damn scary watching the gauge creep into the red 16's when pulling off or poodling around! So, is this completely normal then for my stock J-spec setup ???(with new hybrids and BPU parts but still running Sequential) Thanks Smarty - I really hope you sort this buddy. Fingers crossed for you. As I said, if Chris Wilson flags anything up abnormal in mine I'll give you a shout buddy! Good luck. Greg Quote Link to comment Share on other sites More sharing options...
Ian C Posted October 9, 2006 Share Posted October 9, 2006 AFM code = MAP code on a J-spec. (I believe). I'd swap the sensor and re test. A fault code 35 is the turbo presure sensor. I swear we've been through this before Anyway, easy to test: 1. clear the ECU of error codes 2. unplug your MAP sensor at the sensor itself (not the hose, the wiring plug) 3. fire up the engine and your check engine light should come on (and it'll run like a bag of spanners) 4. Switch off and check your codes again. You'll either get a 31, a 35, or both Let us know! -Ian Quote Link to comment Share on other sites More sharing options...
Steve Posted October 10, 2006 Author Share Posted October 10, 2006 Will check that tonight Ian. I havent changed the Air Temp intake sensor yet. Does anybody know what resistance should be accross this sensor? Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted October 10, 2006 Share Posted October 10, 2006 Not much help now i know, but i did mention a while ago about checking the ECU water temp sensor and the air temp sensor ( I'll have a look in the manual for testing) and i think it was also mentioned about checking the MAP sensor, it always pays to check the small easy to get at bits first;) good luck! You have checked the lambda sensor i take it? Quote Link to comment Share on other sites More sharing options...
Steve Posted October 10, 2006 Author Share Posted October 10, 2006 Have changed the water temp sensor, just need to test the Air temp sensor ( just need the resistance value it should be at ). Ian C has looked at Datalogs from the car and MAP sensor was close to the Greddy Pressure sensor, so dont think it could that. Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted October 10, 2006 Share Posted October 10, 2006 Looked in the manual and afaics the air temp sensor seems to be limited to the US and the UK models, as its in the AFM?? maybe i have missed something in the manual, as i'm sure there is a air temp sensor input wire to the ECU?

Steve Posted October 10, 2006 Author Share Posted October 10, 2006 It is screwed into the plenum near the MAP sensor. Unless that is something else. Quote Link to comment Share on other sites More sharing options...
bondango Posted October 10, 2006 Share Posted October 10, 2006 THA pin on the ECU is the intake temp Voltage, this is the test for the UK spec (though temp sensor is part of AFM) , i dont have the jspec to hand but they *may* be similar spec volatges to the ECU...

Steve Posted March 23, 2007 Author Share Posted March 23, 2007 After looking at every possible fault, i gave up and took the car down to Matt Harwood. Matt had the car for a few weeks trying to find the problem, then thanks to another chat with Ian C, they found that the poxy Wideband sensor was at fault. This was the one thing that i didnt think to check as it was less than a year old. But now its all working fine and after some mapping work by Ian the flies again. Ah well you live and learn Quote Link to comment Share on other sites More sharing options...
RobSheffield Posted March 23, 2007 Share Posted March 23, 2007 Where in the system was the sensor mounted? Quote Link to comment Share on other sites More sharing options...
Steve Posted March 23, 2007 Author Share Posted March 23, 2007 Rob, it was in the second decat pipe, just under the gear stick area. Quote Link to comment Share on other sites More sharing options...
