Ollieh17 Posted August 23, 2014 Posted August 23, 2014 (edited) Have a emanage mapped to 1bar on a td04 with a 3bar map sensor, standard fpr and a walbro fuel pump. On idle the car runs rich, however when i give some throttle it leans out to 15. On boost it drops back down again. But crusing at 11.6. What could cause this? Was fine on standard ecU Edited October 3, 2014 by Ollieh17 Quote
funny onion Posted August 23, 2014 Posted August 23, 2014 did you have the emange mapped or have you just fitted it with the map already on? Quote
Ollieh17 Posted August 23, 2014 Author Posted August 23, 2014 Map was already on and due to get it tweaked. Surely it wont make that much difference to the afrs. With throttle it fuels spot on, boost and off boost. But on idle and crusing drops right down Quote
funny onion Posted August 23, 2014 Posted August 23, 2014 Could be the reason. That's why everyone says never fit an ecu that has someone elses map on it. i'd get the map checked but it could also be TPS i suppose Quote
Ollieh17 Posted August 23, 2014 Author Posted August 23, 2014 Very true. But toyota made one ecu with one map for all glanzas and people use plug and plays all the time. I have the same fuel,pump, boost controller and rrfpr that the guy before had and cant seeing it being that far out Quote
funny onion Posted August 23, 2014 Posted August 23, 2014 yeah but worth getting it checked, i don't rate plug and plays for that reason. just check the obvious stuff, set the TPS with a multimeter, set base timing up with a timing light etc and get the map checked. if it's not misfiring then i wouldn't panic like mad but it is a bit rich and you don't want bore wash lol just boost everywhere haha Quote
TrisK Posted August 23, 2014 Posted August 23, 2014 Very true. But toyota made one ecu with one map for all glanzas and people use plug and plays all the time.

mikey4410 Posted August 23, 2014 Posted August 23, 2014 Tbh I went on a wild goose chase recently with u usually low and high wideband readings.was showing 7 afr at WOT and idle was 18-19 afrtried alsorts of stuff and after weeks of changing parts I looked past the thought of the wideband being at fault.got a new unit and all was fine.widebands do fail sometimes !!!!!!

Ollieh17 Posted August 23, 2014 Author Posted August 23, 2014 Its all fine AFR with standard ecu. Guess ill have to unplug it until map tweak. The wiring diagram i followed has no input/output from tps, is there supposed to be one to the emanage? Quote
Stu Posted August 23, 2014 Posted August 23, 2014 Yeah thats way too rich on idle - basically when I'm setting up new ecu's I lean them right out for idle and cruise (unless its got crazy cams etc) - 15's are about right. You can muck with the ignition maps so the idle sits in a slight ignition map 'hole' and if the revs drop then add more timing to bring the revs back again. Quote
Ollieh17 Posted August 23, 2014 Author Posted August 23, 2014 Reckon its something to do with the throttle position sensor. If im right tuning developments dont map on the tps Quote
maddox710 Posted August 23, 2014 Posted August 23, 2014 Mike from td told me that the lambda sensor needs calibrating ever couple of weeks or so. Which involves taking the sensor out and leave it in fresh air for a couple of minutes obviously with ignition on Quote
Ollieh17 Posted August 23, 2014 Author Posted August 23, 2014 May use my AEM wideband as the main lambda and see if that makes a difference Quote

Which involves taking the sensor out and leave it in fresh air for a couple of minutes obviously with ignition on Wide band free air calibration - dependent on the controller your using there are a couple of different ways of doing it.

Ollieh17 Posted August 23, 2014 Author Posted August 23, 2014 Its fine with a slight bit of throttle its weird Quote
Ollieh17 Posted August 23, 2014 Author Posted August 23, 2014 Its the same with the emanage completely unplugged Quote
mikey4410 Posted August 23, 2014 Posted August 23, 2014 Widebands need calibrating every 10k miles. Or yearly.not weekly or anything close to that lol. Quote
Ollieh17 Posted August 23, 2014 Author Posted August 23, 2014 Thought you didn't have to calibrate AEMS? Quote
mikey4410 Posted August 23, 2014 Posted August 23, 2014 And that.even more so they don't need calibrating. Quote
richardc9052 Posted August 23, 2014 Posted August 23, 2014 (edited) Aems are aupposed to self calibrate without touching them Edited August 23, 2014 by richardc9052 Quote
mikey4410 Posted August 23, 2014 Posted August 23, 2014 The person who got told somebody recalibate's theres weekly will probably find thats on a dyno machine which I totally understand and would do myself. Quote
Ollieh17 Posted August 23, 2014 Author Posted August 23, 2014 Only thing ive changed is fuel pump really Quote
richardc9052 Posted August 23, 2014 Posted August 23, 2014 Fuel pump shouldn't change anything unless your fpr can't handle the increase Quote
richardc9052 Posted August 23, 2014 Posted August 23, 2014 I'll let you know how mine reacts. I'll be fitting a walbro pump in a week or two Quote
