!!!!!Newbie Tuning Question!!!!!

[Gen1boost]

Okay this is kinda of a newbie question but here it goes. In the summer i will be purchasing a super afc and some 660cc injectors. I am currently running a big 16g(on 8lbs), a walbro 255 hp fuel pump, 3"inch custom exhaust. I was wondering in the summer when i get the injectors and the super afc on ... i will be getting it tuned at ams. I was wondering how much boost i can hold. Can i hold a solid 18 for a daily drive. or should i just tell them to tune it for 15? Ive talked to a few tuners who have been running 20+ lbs but they have either blown a motor, or ####ed something else up. I was just wondering what is a safe amount of boost i should have them tune it to?

20 will be fine, I ran 20lbs daily on my bone stock motor with 220,000kms.

PS you can run a few more PSI with your current setup BTW.

Well i was talking to this guy at work, he has a civic with a k20 motor and a big 16g turbo. I was talking to him about tunning and he was saying how its not smart to have 20lbs tunned because i have stock internals and if i blew anything or ####ed up anything the shop would be held accounted for it. So he was trying to say that the shop would probably only tune it for 14-15lbs max with stock internals. Yes i know ... not the best person to ask about tunnin sence he has a civic but oh well thats why i came here haha. anyways just like to say if i could get some more feedback that would be great!!!!!

A stock 4g63 can hold around 400 hp I really dont think you will be seeing that on a b16g just tune it for 20 psi and drive normal during daily driving.

Uhh, unless he's spraying alch or has 94 oct or something i really doubt he's gonna be able to get 20 PSI out of a 16G with out lots of knock


shoot for something like 17-18 max, find out what your set up can hold and go with that, 20 is a bit much for a 16g on pump with YOUR set up.

do you have a front mount? hard upper and lower IC pipes? still on the stock SMIC? if so don't push it.

 

[Gen1boost]

yah thats what i was also thinking. I dont have any hard uicp or licp so yeah, and im still on the stock side mount. so i think ill get it tunned for 18. but thanks alot guys

Tons of people run 20lbs daily on there 16g's


But if you don't have the proper supporting mods then I would suggest 15lbs, also I wouldn't waste your money having it professionally tuned untill you have all your Major mods done. A FMIC will change your tune drastically.

yo if your gonna run 20 psi run with an 18g. and theres no need for 660 injectors those are big, you could but you could save your self some money and get 550 injectors and run 17 to 18 psi on your 16 g and be set. also make sure you get ride of the stock side mount and put atleast a 2gen supra side mount intercooler with hard piping to keep your cfm ratings up in hi numbers. the safc is a nice tool to have, you should also get a electronic boost controler if you plan on running hi boost so while driving slow and nice you can have the boost turned down and tune from your cockpit for races.

i have a greddy profec b spec II that i haven't installed yet

We would generally tune a car like that for about 17-18 psi. The extra 10-15 extra HP you may get by pushing the envelope isnt worth the risk of having to spend thousands of dollars on a new engine.

We have to be careful as a shop as we don't know which people will let off when they feel the car lay down and which ones will just keep their foot in it and not have a clue whats goin on.

yeah i mean i only have a 2g manifold, 1g crushed bov, 3inch exahust, 255 walbro fuel pump (rewired), and the big 16g. I just want to have a slightly fast but daily driver car. Cuz im only 17 and i dont need a low 12second street car for right now. But thanks for the comments. I heard that ams also charged like 150-175$ an hour for tunning ... is this true?

You'll have to get with Eric #1 for tuning prices. I'm a tech and I dont keep up with pricing at all. I do know one reason the price is up there is because of the problems usually associated with tuning, the higher rate of "warranty work, redoing tuning cause of complaints or small issues", and the liability of tuning cars on the road which requires very expensive shop insurance which completly covers the company, employee, and customers car, which 95% of shops probibly DO NOT have. Anyone ever heard of an example of a shop wrapping someones car around a pole and that person have to come out of their own insurance for it?

don't mean to steal the thread but, i just have one question, when tuning with an AFC the settings you put in are there until you change them correct? what about changes in air temp? would you have to "re-tune" the car again to compensate for that unlike the stock ecu wich does that automaticaly? is this the case with all tuning sofware then? except for maybe an eprom ecu flashed to run the proper injectors.

One N, people. Tuning, not tunning.

The safc is a piggyback system, you are still using all the same maps in the stock ecu. It just modifies the air flow signal before it goes into the ecu.
