The car looks like a rs not a gst.There's no side skirts.

It might feel slower at low rpms but you will have more top end. To get the most power out of the 272s you need to tune.

Are you still using the stock cam angle sensor?

I'm not sure about 1gs but I know the 2gs A/C compressor and coil pack plugs are the same, the compressor one should be longer anyways.I would start by checking your power transistor unit.

Yeah sounds like a fuse to me too.Most of the time its something simple like a fuse or a ground.So just check the fuse box under the hood and under the dash and go from there.

Is your bov recirculated? And how are your spark plug and wires.

Stronger timing belt then oem.

Forced Performance does sell oem Mitsubishi parts that they usually do port work on. So they just probably modified it.

Your mind is in the right spot, maintenance first. Check spark plugs(NGK BPR6ES work well) spark plug wires,all filters/oil(I prefer Mobil one synthetic but its up to you really), and a the main one is the timing and balance shaft belt if you don't know when the last time it was changed get a...

Should all bolt right up. Just sometime cheaper downpipes are hard to install cause there not lined up properly.

Have you tried cleaning it? Go get a can of maf sensor cleaner and clean it they get dirty and wont read right.

Maybe a headgasket but try to put a cap full of oil in one of your cylinders and redo the test in that cylinder.

Its more then likely not a typo,extremepsi all most always has the lowest prices,I get my parts from them all the time and never had a problem.

What are all the mods on your car?injectors,fuel pump, tuning device,etc? And do a boost leak test too.

Sounds like the balance shaft belt. It could of got between the timing belt and the crank gear and made it jump timing and possibly bent your valves. Check the timing and see if its off.

Did you gap the plugs? And do a boost leak test.

Just think about it, bigger ports = more air flow, more air flow = more power :thumb: Is he going to do your manifold too? If so then i would do it.

I had the same problem on my old gsx it ended up being the cam sensor. I just did the 1g cas swap and it ran great.:thumb:

Yes they will work fine.

Yeah your probably going to need dsmlink, cause I had the same problem and I just set dsmlink to ignore the misfire and the problem went away.

Sounds like its running rich which is causing it to back fire. Maybe you need to re-tune.

Try changing the cam sensor.

My car does the same thing till it warms up but I haven't found anything wrong with my car so i just deal with it. Just let it warm up.

Yeah, it looks like the original one, so it's probably no good. Do you recommend a curtain brand?

I got the VR speed fmic and so far so good.The only bad part I see is you have to cut your front core support alittle.

OK here's another log.

Yeah it works, should I go drive and log it?

OK guys thanks for your help.I'm sure i'll eventually figure it out.Ok ill get one later on tonight .Here's one.

So basically just start adjusting the air and fuel trims?

Yeah I saw that too but I tried both 210 and 315 and no change.

Yeah correct (91 octane). What do I need to log to adjust the airflow?

Oh ok, ill try that and log it in a little bit. And im sorry im sure its posted some where but I cant find out how to post a log on here.

The car is fully warmed up when I log (194 degrees when driving and around 204 parked). My global is -31 and deadtime is 315,so go like -38?All my settings are at zero (fuel trims,timing,and airflow sliders).

OK that's my problem, mine doesn't change they both stay at 12.5% no matter what I change.

Isn't the LTFT Lo and mid supposed to change when I adjust the global or deadtime?

That's what I thought. Dsmlink user manual says to get the global and deadtime adjusted first by LTFT idle and LTFT cruise (which im guessing is LTFT Lo and LTFT Mid) and then it says to adjust WOT after.

ok ill log it tomorrow and post it up.But im supposed to log LTFT Lo and LTFT Hi to determine where to adjust the global and dead time right?

fuel injector clinic 650cc

All my fuel, timing and airflow are all at zero i havent adjusted anything yet can that be my problem?

i know the base global and deadtime of where to start at but im supposed to fine tune global and deadtime for my injectors by having LTFT Lo and LTFT Hi around 0% and im at 12.5% and they are supposed to changed if i adjust the global or deadtime settings but there not they just stay at 12.5%...

Hi everybody, ive been searching everywhere and i cant seem to figure out how to set the global and deadtime for my injectors im logging LTFT Lo and LTFT Hi and there both saying 12.5% and they wont changed no matter if i change the global or deadtime setting. Im following dsmlink guide to the...

yeah listen to everyone just get lowering springs or coil over, you will more then likely run into problems.

It could be the headgasket ,warped head, or head might be cracked.I would take it off and take it to a machine shop and have them check it.

How old are your spark plug wires? Even though they look good it doesnt mean that are. Just try a tune up (spark plugs/wires,fuel filter,etc) gap the spark plugs and a boost leak test and see if that works.

when the motor is cold it runs rich till it warms up and that would cause it to back fire

there no hard to make you can buy all of the parts at home depot,unless you wanted to meet up i can help you. im in hesperia,just pm me

Look here to figure out if your ecu has eprom, http://www.dsmtuners.com/forums/articles-tuning-ecu/381713-1g-ecu-eprom-vs-non-eprom-visual-comparison.html?highlight=eprom+ecuIf it does you still need to get it socketed,its usually like 30 bucks

I say either black or white but the down side of black is hotter in the summer and you can never keep it clean :(

No i just payed 3200 for mine and it has more done to it and less miles
