I'm maf only, never had an issue. One day I'll stop being lazy and SD tune it, since my maf is maxed out, but ohh well.

Never moved the coolant hoses. Never bothered me. They don't cause an issue, so was never worried about them there. Only thing I really changed was I had one of the nutserts pop out that holds the lower pipe on. Instead of running to hardware store and getting another I just used zip ties there. Cheap/easy and it works.

SD will definitely help, but no reason a maf can't work just fine. That is all tuning issues though.

 

I had that nutsert pop out too. Never did like the angle that they weld that bracket on but oh well.

Maybe it's just a matter of messing with the charge tube positioning like Doug mentioned to help with getting a stable MAF signal

 

Yes they did, we discussed the same things you and I did on the phone. I'm not sure where it will go from there though.


I'll be glad to either send a tune file if the user has EFI live, or just send in your ECM and I'll drop a file in it for you.

ECS customers get this as a N/C service as a thank you for purchasing our supercharger system.

Thanks for your business! We had several kits leave yesterday, PM me your name and I'll let you know if/when it has left.

Thanks for your business as well, anything I can do to assist just ask.

Thanks!

As Nick said below, we have several tuners who only tune MAF, but unfortunately I'm not one of them so I'm not the best help here. I wish I could offer more help other then what the MAF tuners have told me. (rotate the charge tube slightly if readings are inaccurate)

Glad to hear that from one of the regulars here.


This is the second time I have been told this recently, I'll look into possibly making a change to that. Thanks for the heads up.

 

As far as the nurserts go, we didn't use them. We drilled through and used a bolt and locknut.

I don't think the shop is willing to tune it in SD. They are saying there are disadvantages to it. They will be testing my car with a honeycomb before the maf in the near future to see if it helps.

I just want it right. I'm sure both the MAF tune and SD tuning are great. I'd rather not spend more money when I just dropped 600 for a tune.

 

Maybe I should start tuning on SD this afternoon. May have to bug Doug on what settings to swap over to run SD.

Retuning the car so now is a good time.

 

You use EFI live correct? I'll send a good base file over to you to get started if so.

 

HP tuners. Running the 2.5 bar os with 2.5 bar map sensor. I'll email a tune over later If you want to just do some quick edits or explain what to swap over to run SD only.

My SD tuning went as far as I forgot to plug the maf in one day and drove to gym and couldn't figure out why car was running a lean.

Just emailed Doug my tune.

 

For C6's I do not have any files in HP unfortunately, only EFI. Let me shoot a message over to Matt @ FSP and see what he has for you. He is an HP guy.

 

If you really want to get fancy you can come up with a PID that takes MAF flow data & AFR error and generates a VE table

If what you have already is close enough for it to run then it just throw it in closed loop, log fuel trims/wideband and have at it

 

That would be a great option since he has the car tuned already. Save some time.

 

Too lazy. Matt already on top of it as expected

 

That's ok, mine took exactly 6 weeks!!! Patience is a virtue and it was well worth the wait.

 

So I'm a little frustrated at this point and don't want to put my tuner on blast.

I paid 50 bucks for a basemap to drive the vehicle from my shop to the tuner (12 miles). The base map was ****. Couldn't get past 2000 rpms. I was scared we messed up something but we were sure we were on point with the install. Get it there by towing it which was an extra 125 out of pocket. No biggie. Nothing wrong with the car and they claim the base map was fine. I'm telling you I wouldn't drive this car 4 blocks let alone 12 miles.

Whatever. Done deal.

They tune the car and all good. Doesn't make the power I hoped but it's done so whatever. Go pick it up and they go "just so you know you will have some slight surging due to the supercharger." Uh??? Never read about that online. Get the car. First stand second gear are no fun to drive. You can't accelerate slowly and driving in traffic is next to impossible. It jerks a ton. Higher gears and speeds you don't notice it as much but you can feel the kick back will.

Next day I get a check engine light with Evap and catalyst codes. 7 codes. I bring it back and they do whatever to it and say it was no biggie it's taken care of. They also look at this surging and say that there is nothing they can do in the tune that it's a maf issue. They tune via the MAF.
So I paid 600 for a tune. 50 for a base map that doesn't work. And 125 for a tow to get a tune that isn't right.

So they talk with Doug at ECS who has been wonderful to me and I'm sure to them as well.

I get a call and everyone decides they want to re do the tune in speed density. But they want an extra 200 bucks to do it.

Why should I have to incure an extra 200 bucks after all of this crap has already happened? Instead of finding a solution they keep getting on the defense and get more money out of me. This is not right.

 

Yep, that sucks. Tuner should not be doing that. If they can't get it to run right on maf, they should SD it for no charge.

 

sorry to hear that's tough! I mean for the amount of information said shop is learning from your vehicle (going SD and talking to Doug @ ECS) you think that would be worth the $200 to the shop. Negotiate with them and see what you can do. Best of luck!

I had surging issues (not as bad as you describe). It would accelerate smoothly but trying to hold a set speed (35, 40, etc.) the car would surge (felt almost like a small misfire). We went speed density and it never happened again. Car drove like stock when driven normally. I'm almost certain going SD you'll be more than happy.

 

Hold your position, and advise them that you wont pay for fixing their errors! Since you asked for a SD tune in the first place!! Good luck!

 

Yeah that's bull ****. Doug has offered more than once on here to provide a good starting point SD tune at no charge to others with the ECS kit

If I were that shop, having that base file alone would be worth $200. I'd also bet his base tune in SD could have been dialed in faster than their MAF tune starting from scratch

Kind of worries me they couldn't get you a base file that was close enough to get you to their shop.

Who is tuning this thing? PM me if you don't want to post it. I'd love a copy of the tune if you can get your hands on it.

Bottom line is they want to be lazy. MAF tables are much smaller so it's quicker to dial them in.

 

Doug and Matt offered to get me a map for the tuner to use, and they refused. They want to start from scratch and do it themselves. Why I'll never understand. Im gonna keep fighting about paying the difference for the tune due to all of the issues, but I doublt anything will come of it.

If I take it somewhere else ill be out another 600+ dollars, so I might as well just let them make it right.

Ill keep this updated. Trying to remain calm with all of this. Got home from traveling for work and drove it today. Its disheartening the way first and second gear are. They cant get me in until first week of november. Thank god Im never around M-F or I'd be getting real impatient too.

 

I hear you about having to pay for another tune, but really i wouldn't let this shop even touch my car after all this, that painted a good idea how they proceed with pretty much everything!

 

pay by credit card? Dispute the charge and take it from there and bring the car elsewhere.

There's reasons I like buying things on a credit card and a charge back, if necessary, is one of the main reasons I using one.
