Hey,  i have a 98 wrx, my link G1 was working fine, but 2 months ago i broke my engine, so the car has been without use for 2 months, now everything is fine again, but mu ECU is nos controling my boost anymore. Does any of you have had the same problema? any idea what could have happened?  thanks for your help.  J. Andrinich

Hello, Â i have a 98 WRX, want to get at least 350hp to the motor, actually i have a td05 turbo from the 96 Sti, have header, uppipe, downpipe, injectors, short ram intake, turbo inlet hose, etc. Any recomendations? i am boosting 15psi in 1st gear, 19psi in 2nd and 21psi in the other gears.

I meant  1. injection wake up pulse = 4 2. Injectiors pulse width = 150  what happens if i change any one these 2 parameters?  thank you

Hello, i have a 1998 Impreza WRX (GC8). I am runing a td05-16g at 20psi, my fuel injection duty cycle is marking 99%, i guess it is on it top. Well i have a G1 possum link ECU, from i think it is a WRX99R and i have 2 different options that i do not know exactly how they work: 1. the first one is a fuel injection pulse (showing 4) 2. the second one is a fuel injection with (showing 150) i want to increase boost to 22psi, also thinking of buyin a bigger fuel pump, but i want to know if this 2 options would help me to have a better injection duty cycle. if any can help me. thank you for your time.

this is my latest map, chek it out please! Â i will wait for commets!

in this second file you will se a resume from your MAP, you will see in light blue the different options you have and i dont and in yellow you will see the differences in our settings

i am uploading some resumes from the PCLINK software, the first one is from my MAP, in light blue you will see the different options i have and you dont, and in yellow you will see the differences in our settings.

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

i have the possum linl WRX99R too, but what I know is that we cant have antilag or launch, I have bigger injectors and everything work fine (99 sti injectors).

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).

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.

did you get any person to help you?

what was your final map?

i dont get it lol, mine is older or newer tan yours? email: [email protected] would be good if you send me and Word file with te screen shots of what your see when you log in to your PCLINK.

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

basicaly this is my setting: MASTER FUEL : 85 FUELING: FROM 250RPM TO 7750 (GAPS OF 500RPM) ROW 1 (15MPa): 104,104,104,106,108,108,110,110,110,97,97,97,97,97,97,97 ROW 2 (45MPa): 105,105,104,104,97,97,98,99,99,99,101,101,101,101,101,101 ROW 3 (75MPa): 105,104,104,98,97,97,99,101,102,102,103,104.

OK, soy by what i see you can't open my uploaded maps. Well i will try to send you the info by message. 1998 Subaru Impreza GT, EJ20 engine, td04 turbo, 1998 STI yellow injectors, HKS air filter. G1 POSSUM-LINK ECU. MANUAL BOOST CONTROLER FORGE AT 15PSI. Im sending you a Word file with the pictures of what i see when i hookup mi laptop to mi ECU. Â

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.

here is the other map HIGH

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
