2G DSM link v2.5 help...

[Jammin'Trey]

I bought a 1999 eclipse GSX, it has a 14b, big fmic, all 2.5in hard piping, BM fuel reg, walbro 255, stock 450cc injectors, megan 3in dp, thermal 3in catback, I have an autometer boost/vacuum gauge hooked up aswell. K&N intake. There might be more I am forgetting.... Stock 02 housing.

The car came with an Eprom ecu, and a laptop with dsmlink v2.5, I have done idle datalogging, and a 3rd gear 2k-redline pull thats logged. The car runs about 18psi, I am trying to figure out if it running lean at 18psi, It goes to 15psi then creeps to 18psi (around 5k)according to my autometer phantom gauge (hooked up correctly, t'd on the fp reg vacuum line...). Car pulls hard but falls off power at high rpms.

I am trying to get the datalog from the laptop I got with the car to this one but the other doesnt have wireless, nor can I post in the tuning section....(grr)

On the datalog I got a max of .4 degrees of knock at 5k rpms. The front o2 stabilized at .92v open loop. Thanks.

Ok I did a 3rd gear pull today, 11.2 afr wot (innovate lc-1), Inj duty was 91% at 7k (stock 450cc).

SO I went ahead and started tuning at cruise. I cam up with 15 increase on inj delat, -2.1% on the 150hz slider, not my ltft low and mid are +-.5%, I am happy with that.

I am going to hook up my LC-1 to my ecu here in a minute and go do a 3rd gear pull, When I did the third gear pull earlier I had almost 20 degrees of timing at 7k, That makes me happy... But I had about .4 degrees of knock that came and went around 5k. No knock at full throttle.

When I go do the other 3rd gear pull I will post it up, 2k-7k, I will try to get my intake temps down when i pull and my coolant temps too.

my laptop died when I was streaming on the way home, now my abs light is flashing and I recharged the laptop and now it wont connect to dsmlink. WTF.

I adjusted it so that it is 44 psi fuel pump on motor not running. Then I started the motor and guess what, fuel pressure stays the same at 43psi. Maybe 1 psi or so less (43psi).

Strange. Am I ok running 44psi at idle with stock injectors? The only thing i can think of is my walbro 255 is hard for the B&M to step down with vacuum...

WOe, woe. You're FPR isn't adjusting for manifold pressure. You shouldn't be going WOT without replacing it or fixing it.

Ok, cool. This sucks.

My fuel pressure regulator is broke, my dome lights wont turn on, neither will my radio, my ABS light came on and dsmlink wont connect, car idles like shit.

All these things happened when my laptop died when I was logging.

Welcome the the world of DSM

Ok everything is fixed but the fuel pressure regulator.

Whats the best alternative, I have no big hp plans... (300awhp)... SO what fuel regulator should I buy.

Man I need to buy a aluminum radiator and new fans too. This suuuucks.


I wish my B&M would just work
