  1. Attached is a copy of the current base map and a 10 min idle log after cold start. The only way I can get the car to run somewhat normal is by unplugging my IAT sensor. in the log i connect the sensor a few times and car dies. The car was remotely tuned over a year ago and has never had an issue. From my understanding it is running off my AEM Uego ? I was wondering if maybe my Bosch LSU 4.9 O2 sensor may be in need of replacement. Thank you all in advance. issue with iat.pclr log issue with iat.llg
  2. Good day everyone, I have a G4+ plugin ECU for a 1991 Toyota MR2. The car has been running well for over a year with no issues. One Monday I start the car like any other time and it runs as expected for the small local trip. I get home and park until the next day. The following day i start up the car no problem. warms up like normal. i pull out of driveway and all of a sudden car bogs and stalls. i barely make it around the block and park in driveway. now when i start it barely runs before stalling. I hook up the laptop and connect to Ecu. The only way I can get car to idle somewhat normally (15.6 AFR) is by unplugging IAT sensor which gives a IAT of -40 degrees Celsius. from my understanding, doing this adds fuel? somethings i noticed and have questions about are the general runtime values MAP (psi) and MGP (psi). When i unplug the IAT and engine idle smooths out, I noticed MAP at 6.8 psi and MGP at -7.4 psi. my external Boost gauge reads -21" wc (which is normal) when i reconnect IAT, MAP reads 11.6 psi idle becomes rough and my external boost gauge drops to - 8-10" wc. Can someone clarify which parameter, if any, MAP or MGP is suppose to match my boost gauge? all these readings are at idle. Im beginning to question the MAP sensor. I am using the MAP sensor provided by CRW when I bought the ECU last year. There are no part numbers on the sensor. sensor type selected was Cal 5. Can someone point me in the right direction?
  3. As far as making adjustments on my fuel table at idle, what's an adequate procedure for trimming down fuel? I was thinking -5% offset for my 800- 1000 rpm column for a starting point. Any better ideas? Thanks everyone
  4. Thank you Scott, I will give that a shot tomorrow and post any changes.
  5. Thank you for the quick response. I'm actually at the Far East coast in nyc. I'll pm you now. Thanks again.
  6. hello everyone , i am the proud new owner of a G4+ plugin ECU on my 91 mr2 turbo. I noticed my idle is very rich. it stays this way even after warm up. my lambda target is set to .95 but the actual never leaves .67. Anyone have any tips on how to lower this. would i adjust my fuel table by trying -5 across the table? or is there a better way. i just want to clear up my idle so my neighbors stop complaining. i plan on getting it tuned by a reputable dealer here in the states. just want to drive it around the block and get it to idle better. Thanks for the help!
