Hey guys, I have some problems now that I got back from Detroit getting some work done on my car at Godspeed. Please I don't need to hear any critisism about this, I just need some help. So I went out to Godspeed to get alot of work done and get tuned. On the dyno there were no problems and I came out with 300whp. On the way home I smelt gas strongly, pulled over and noticed fuel spraying out of one of my injectors. To make that shorter they installed the 800cc injectors with the stock seals and o-rings without lubing them before install. I replaced the seals and rings. Then the car started mis-fireing under high load and had a boost leak. We found the boost leak to be a selenoid that was entirely broken in half and looked like someone had tried to glue it back together but didnt hold, replaced that. I just installed new spark plugs yesterday and noticed 3 were crappy autolites that didnt look like they were even gapped and 1 was a stock plug... Now the car doesnt misfire but it still has black smoke come out the exhaust when ever I give it some decent gas and it still doesnt boost past around 10lbs. I do have a manual boost controller on it right now because I forgot to bring the UTEC boost controller with me. I want to know if someone could help me with putting that on and take a look at the tune, because it was tuned with the injectors had bad seals. Oh also, when I come to a complete stop, it sometime revs and almost dies by itself, almost like its not getting enough fuel because it looks like the idle drops below 400rpms. If anyone knows of anyone that could help me out that would be great, or if it sounds like I just need to take it to DB Performace or RS Motors to get a good tune lemme know.
are you the car's first owner? I've never heard much bad about godspeed before... did they install the injectors or did you or did the previous owner?
I bought the car bone stock, 2nd owner. They installed the injectors, Godspeed is a great shop, if your planning on spending over $20,000.... When we tried to make Godspeed pay for the cost of puting in new seals with labor(because I was in the middle of no where) they didn't want to pay. We got a lawyer on the phone and Dan (Godspeed owner) was very rude and cocky to my father and me and our lawyer. When my dad said, my son spent alot of money with you guys $8,000, Dan's response was, that's nothing to me.
damn. I have had some interactions with them and dan seemed nice enough to me. I gues things change when money is on the line. Too bad, he's one of the only guys in the USA who will tune my link, thankfully one of the other guys is coming to do it this weekend =] I was actually planning on going down there myself to get some work done. Not looking ultra likely now.
if you could post a complete list of your power-related mods only that would probably help people offer useful advice. To right your ship in the ignition department, get one step colder plugs, gap them to .028, throw them in. Choice of copper/iridium/other is up to you, I'm not going to rehash the spark plug wars here. I would advise against using a manual boost controller. The UTEC can handle boost control just fine on its own, and in all likelihood you do not even need the auxiliary boost controller (ABC) that it came with that you referred to not having at the time of your tune. This part is only required if you cannot reach your target boost with the factory boost controller and UTEC working in tandem. You may want to consider going the route of the GM boost control solenoid (search NASIOC for this, extensive info available; or contact one of the several locals who run one). It sounds like your fuel trims are badly out of whack and if you can't boost past 10 lbs, you could have the restrictor in the wrong vacuum line, a dead coil pack, or something like that. In any case, I wouldn't recommend romping on it at all in its current state, hopefully that is common sense. Shame to go all that way and get such lousy service...but unlike esperunit I've heard more than a few tales of dodgy dealings with Godspeed.
I allready replaced the spark plugs with NGK Iridium One Step Colder last night. I also know that manual boost controllers on these cars are not recommended and I had planned on running all boost control through my UTEC, sadly that's the one part I forgot when we went to Godspeed, we were running 19.5 psi so the stock one couldnt handle it. As for power mods. I think thats all Deadbolt 18G TD05 3" TBE Up-pipe APS TMIC & BOV Koyo Radiatior PE800cc injectors Fuel Pump Samco Inlet Hose UTEC RA Gear Tranny, ACT Flywheel, Exedy Clutch
Did you do anything else to the car afterwards that could have resulted in the condition of your car, or is it completely their work that made your car run bad? I can't believe a tuner as they are is not taking responsibility over this. You drove right out of their store and your car developed problems on the way home. Obviously it's their fault and they must adhere to that. If they persist to deny your concerns as a customer of theirs, go to NASIOC, I-Club, etc. and express your issue of their bad business practices.
It's a really tough situation. The injectors they took responsibility for because they were sealed when I left Godspeed, and the leak didnt open up until I got on the highway, which makes sense. It didn't have any other problems until I got to Subaru in South Bend Indiana to replace the seals. Before I even found out about the leaky injectors it had a slight misfire at high load on the highway, but I fixed that. I've looked all over where he (subaru) would have been working by the 2 injectors on the passanger side. I don't know everything about the vacuum lines or exactly which one goes where, that's why I want someone to look over the car.
Wow, sounds like Dogspeed pissed on your parade! WTF. "Dan's response was, that's nothing to me." My response would have been, "Die in a fire. c0ck first." Then sick the lawyers on him. 8 grand is nothing to him...oh, then he probably wont mind if you take twice that plus legal fees.
After Dan said that, my dad responded with, my son is 19 years old, and 8 grand is alot of money, then he did appologize but it shouldnt have been said in the first place agreed.
Well, your idleing issues are because of the pe injectors. get used to it, and welcome to the world of pe injectors. There really isn't much you will be able to do about the idle stuff, as for the rest of the issues, you could pull a couple of logs and post them up so we can take a look at them. Just make sure you use log number 1. Russ
Actually the idling problem is not because of the brand of injector, or the size. I've done plenty of research and asked plenty of users. They said the idle is worse then some other brands but should not be revving to 1500 then down to around 200, a sputter every now and then was the most common thing i've heard of.
the fuel trims you can have russ work on. the misfires on load could be from poorly gapped cheap plugs. they also could be from the erroneous afr's you had. for the boost. i'm on the stock unit now with 20.5 psi. the stock unit will handle 19.5 psi no problem. like zola pointed out, it could have been a leak or mis plummed line.pil from the get go. track down the problem and do either the abc or a gm b/cunit. you will need to redo your boost gain, and probobly your maps too. russ and matt are very good people to have on speed dial.
Assuming you can get everything working properly (mechanically speaking), you could try pdx tuning for a map. That and posting your log will be your best bet.
Well, your hunting idle is due to the pe injectors. You can ask a few memeber on here that have seen them (or had them). You will not get away from that. I might be able to tune it a bit so it is not as bad, but it will always be there. Again, I suggest that you pull a log and we can disect it from there. Russ
Sorry I dont have anything to pull a log, or even know what that is.... I'm not very knowlegable on the Electronics side of cars.....
If it is mostly the injectors that are creating the problem, what kind would you suggest. I've heard good things about Ultimate Racing, thier website has alot of injectors to choose from. I'm sure the 680cc's would be fine, but there are 2 different kinds.... One set flow matched within 1% and one set flow matched to each cylinder.
Well, with my 18g at 22psi my 630cc injectors run around 90-91% idc's, so I would say you want to make sure you have atleast that. Do you still have your stock injectors?? I can mod them for ya to 630 or 680cc (or cut the caps for 820cc). Or you could try finding a set of stocker that I could mod. The ultimate racing injectors are very good injectors, but you will need to wire in a resistor box. As for which set of injecotrs to go with, get the cylinder matched set if you are still using the stock fuel rails. Russ
Easy to remedy. Tactrix.com sells the openport 1.2, which is a cable that runs from your laptop USB port to your OBDII port under the dash (where your knees sometimes hit). Using the cable and ECU explorer and TunerPro (both downloadable freeware), you can read the ROM flash settings of your ECU and change them to your heart's content (or F up your car). You can also drive around and record data from the ECU taken by all of your various sensors. That data is called a log (from datalog I guess). With the log, which shows almost everything, like Throttle Position Sensor Opening, Wastegate Duty Cycle, Airflow, Boost, Speed, RPM, Ignition, etc., we can dissect what your car is doing. We can also, with TunerPro, check your ECU map settings and see if something is wrong. I have a Tactrix cable, but WallofTVs is borrowing it now. You can PM him and see if he has time to hook it up and grab some logs.
Or even simpler, since he has a UTEC...hook up a laptop and use logger #1. All of the information required to do very basic logging is in the UTEC manual (downloadable in PDF format from TXS website).
I was confused about that. He said he had a manual boost controller on it now, but also said he had a Utec boost controller. I thought he was referring to the DTEC boost controller, since he said he didn't know much about electronics. Mea culpa.
Yup, just use the tuna to log. I'm guessing that both the tune and some mechanical stuff is borked. Sure the tune might have been good on the dyno, but it was probably tuned to borked injectors. Methinks your best bet is to have some of the locals take a look at the mech. stuff, and then have Russ retune it.
PDX only does "e-tuning" with the accessport. He'd have to drive out to Portland for them to monkey with his Utec.
ok, I don't have a laptop...... and yes I do have a manual boost controller in use right now, but I also have the thing used with UTEC for controlling boost NOT hooked up, but I want that hooked up instead of my manual boost controller
Huge thanks to Russ for helping me out last night. Turns out my UTEC wasnt even running my car, somehow the switch got screwed up and said it was on map 0 when it showed map 1.
Yeah its running very well now, i have the boost up to 16lbs right now, its still a lil too wet to turn it up anymore.
