How the hell are my injectors maxed out at 8 psi?? Help needed. Thanks.

Ignore the msq. The second pic is a shot at 166 kpa. DC for 460 is 100. Can I be really flowing that much more air??

Sounds like a fuel pump and/or regulator problem to me. Do a fuel pressure check.

Okay thanks... I just got back from school. I missed the bus so I had to drive. Now the tach doesn't work. I'm definitely having electrical issues. I am using a regular duralast battery and I think is shitting itself. My gauges were working poorly, and when the power when off the markings matched MS.... :facepalm:

VE values in boost have almost doubled.

Do you have the vac/pressure line on the FPR connected?

Are the VE values out of boost, exactly the same?

Yes, and out of boost there's nothing unusual.

Here is my msq

Clos561 09-01-2011 09:28 PM

how many miles did the block have when it went boom

buffon01 09-01-2011 09:39 PM

The old one? 160K? I don't recall exactly... Why?

Clos561 09-01-2011 10:29 PM

just curios, cuz i just boosted my car. 154k on the clock lol

shuiend 09-01-2011 10:52 PM

Are you running cops or stock coils? If you are running the stock coils could you look at one of the plugs that plugs into the coil pack and tell me if it is 3 or 4 wire?

On 90-95.5 the tach is driven off the coils, in the later years it is driven off the ecu.

Oh, don't worry. I blew up because I had a SHITTYYYYY tune and I was beating the care like I stole it AND my engine was weak already. You should be fine.

Stock coils. I know my car is the one that the tach works with the resistor in the diagnostic box. I think the problem with the tach was voltage. I reviewed my log and I wast oscillating between 10 and 11 volts all the way home. I think my battery got disconnected somehow.

Okey, I just bought a 255lhp guel pump from Railz and I am now debating whether I should but 550cc or 800cc injectors. Anyone wants to chime in?

pusha 09-04-2011 01:36 AM

ID1000s!!!

buffon01 09-05-2011 10:55 PM

... anyone else?

EV14 660-1000cc

what turbo?



what are your current injectors? that log posted above is fucked up.

buffon01 09-06-2011 10:14 PM

I'm going to get railz' DW1000. This is the set up:

99 block and head
MS built by Brain
460cc injectors
Stock fuel rail and pump
GT2870 (churbo) 15 psi internal wastegate
AbsurdFlow tubular low mount mani
3" turbo back straight pipe

Regarding to the tune, yesterday I modded a base map. At first, I tried to do it through TS and I got a lot of error messages. TS is set to HR_10 and I followed the steps to set it up according to my MS. After I did the same in Megatune and I did not have a single issue. Suggestions? Thanks

buffon01 09-11-2011 08:47 PM

Update. The leaks appear to be fixed now. My alternator seems to have taken a shit. Hopefully I get up of my couch sometime this week to take alternator out and take it to have it replaced.

Anyone wants to input on the TS issue?

viperormiata 09-11-2011 09:24 PM

I really, really want to get my hands on your MS(ass) and figure this shit out. Serious. It's not even my car and I'm getting frustrated, lol.

buffon01 09-13-2011 11:41 PM

I don't even know if it's the MS. Megatune works fine but TS doesn't. I get error messages that I did not get before and TS is set up with the correct firmware :dunno:
