Jose Andrinich Posted April 17, 2013 Report Share Posted April 17, 2013 Hey guys, i am new here, I bought a Subaru Impreza GT 1998, it is like the WRX but it has less power, only 220hp. Well the car came with a PossumLink ECU, the problem is that i cant drive on full boost, the AFR is too lean. It has the STD map and also de HIGH map, both are having troubles.  STD map gives me an AFR of 17 and at normal driving it is between 13 and 15 but if i hit the gas it inmeditely goes 16 or 17 and start to fail, this happens at 10psi (lowest) and 16psi (highest) HIGH map gives me an AFR of 10 and the iddle is super inestable, the car smokes a lot like a diesel engine, when normal driving the car gives AFR between 12 and 14 but when i lift the foot from the gas the iddle goes down to 200-300rpm and sometimes the engine stops. When hard driving, the AFR is between 14 and 15.5 (lean) but it runs better than the STD map. I have only test this map at 12psi, in this case if i lift the foot from the gas the engines always stops. Need a lot of help! this car is new for me, it is difficult to undestand this G1 ECU i have worked with and 2003 sti and it is much easier. if anyone has any advise, please let me know. I can upload both maps if it is necessary. thank you all! gt1.pcl Quote Link to comment Share on other sites More sharing options...
Jose Andrinich Posted April 17, 2013 Author Report Share Posted April 17, 2013 here is the other map HIGH Quote Link to comment Share on other sites More sharing options...
Simon Posted April 22, 2013 Report Share Posted April 22, 2013 Looking at the MAP the fuel numbers look too big at low load the numbers are so flat going down the table. It looks to need some time spent tuning. You can tune in real time so if you drive the car and work through the fuel map starting at light load and working up to higher load. Try to adjust only when you are in a zone centre. Quote Link to comment Share on other sites More sharing options...
neil brown Posted May 5, 2013 Report Share Posted May 5, 2013 what is your car running  is it a td04 turbo, black intercooler, grey injectors  if so can supply a map if car standard, as running a g1 link ecu can supply 6 rows of fuel info, 6 rows of ign info, boost guide, waste gate control Quote Link to comment Share on other sites More sharing options...
Jose Andrinich Posted July 22, 2013 Author Report Share Posted July 22, 2013 Hey, thank you all for your replys. Â Well i tried to fix the problema, i am not an expert doing this mapping, but here my latest upgrade. It is a map done by me, working at 15psi. Timing tables hasnt change, just did modificatin to teh fueling. Please is any of you guys can help me. Mi Impreza has yellow injectors and HKS air filter, the all the other stuff is OEM. Please Neil send me your values or complete map to upload it to my ECU. If any of you have time to check my ECU map, please i would like to hear your comments. I guess i need more modification in timing table and also fueling tables. Quote Link to comment Share on other sites More sharing options...

neil brown Posted July 29, 2013 Report Share Posted July 29, 2013 you need to let link ecu control the boost  your tps needs calibrated with low tps around 10 and high tps around 100  why does your system volts say 21.6 volts if you are on a 12v dc system  are you a g1 ecu as you have 10 rows of fuel and ign, were my ecu only has 6 rows  can supply details but you would have to fill in some gaps  got two maps  map 1 - td04, sti intercooler, ngk 6's, grey injectors (380cc) around 270nhp on 1.35bar boost with cat downpipe map 2 - vf28, sti intercooler, ngk 7's, yellow injectors (440cc), ported headers, ported up pipe, no cats, 1.4 bar boost 337bhp Quote Link to comment Share on other sites More sharing options...
Jose Andrinich Posted July 29, 2013 Author Report Share Posted July 29, 2013 Neil, can you send me both MAPs? so i can check them out? Here i send you a picture of my ECU BOARD, so you can see what i have, i think it is a G1 anf that but the ex-owner told me too. The boost you mention in yous maps is total boost? o you have to add the atmospheric pressure to them? Because the manual says maximun 18psi = 1.25bar (aprox) Â Quote Link to comment Share on other sites More sharing options...
neil brown Posted July 29, 2013 Report Share Posted July 29, 2013 you have a very late g1 ecu  my chip says wrx97R on it and got different numbers underneath wrx97r  will do some screen dumps for you for both maps  where abouts are you ?

neil brown Posted July 29, 2013 Report Share Posted July 29, 2013 boost setting is 235 kpa, which is 1.35 bar (19.85 psi) Â Â Quote Link to comment Share on other sites More sharing options...

Jose Andrinich Posted July 31, 2013 Author Report Share Posted July 31, 2013 Thank you Neil! I got both maps. Unfortunately i think i can not download them to my ECU. Now that i have checked them i have more questions. How can you run your WRX with a Base fuel of 70? mine does not even starts! i run mines with 85 on base fuel. Other question is, why do you have your TPS HIGH at 61 and TPS LOW at 0 ?, i have TPS LOW 253 and HI 61. Quote Link to comment Share on other sites More sharing options...
Jose Andrinich Posted July 31, 2013 Author Report Share Posted July 31, 2013 Well i still dont understand how to set the TPS. Mine says 253 and 61 for low and high. Actually im living in Peru in a city that is about 2500 metres above sea level, from what i know i should use less fuel than anybody that is in the coast, but as i told you my car wont work with less than 80 as a base fuel, last night i tried to put 70 and start the engine but it did not work. My car has the oem td04 turbo, yellow sti injectors (440cc) and a bosh fuel pump that i think it is the same as the oem, same fuel pressure (42psi) and same pumping capacity (180lph).

Simon Posted July 31, 2013 Report Share Posted July 31, 2013 On the PC you will need to adjust the high and low figures till the TPS reading moves between 10-100. Quote Link to comment Share on other sites More sharing options...
Jose Andrinich Posted August 14, 2013 Author Report Share Posted August 14, 2013 i will reconnect my solenoid and eliminate my MBC, but here i have a problem. i am missing some kind of restrictor called "pill" http://www.perth-wrx.com/vb/mechanicals/48287-restrictor-pill-what-why-you-need.html Quote Link to comment Share on other sites More sharing options...
Simon Posted August 16, 2013 Report Share Posted August 16, 2013 On the hand control the TPS set up will be easier then on the PC. You can just use the adjust keys with throttle closed and then open to get 10 - 100. Once done make sure you do a store. A "Pill" Is only required if you are using a two port boost control solenoid.
