D15 B7 turbo
 

I have a 95 civic D15B7 stock internals, and was just rebuilt. and I have a TD05-12B turbo, which is very small. I'm looking to make about 170ish HP. and I need to find a cheap fuel management system. I'm thinking, FMU, cause there is NOWHERE around here to get it tuned or dynoed. so what ratio fmu would I use or is anything fairly cheap I can use?
and please don't say to spend the money and get a standalone system,cause I have no money.

umm anyone? please?

they all generally have a 12:1 ratio, but you should try getting on some of the tuning forums and learn to tune yourself. Its fairly simple if you have a basic understanding on how an engine functions, and with the help of people online you would definantly have better reliability, drivability, etc... Hopefully that helps.

tuning is an art-form. it requires skill, training and practice. i would not attempt to tune yourself. safe yourself the headache and a blown motor and pay someone to do it.

He said he has no money and no-one available around his area to tune it for him, so in response I told him to do some research and merely try it out. What did all tuners never have a first attempt, and not to mention the amount of base maps available at sites such as Phearable.net make tuning a car tuned by multiple people all over the world even easier. Your statement is a complete joke thats like saying the only people able to tune a vehicle are those already doing so, if he does the proper research and gets a decent base map then he's golden. It's not like engines are some exacting science their large air pumps. How about you stick to taking your ---- to a shop and handing over your paycheck, but dont knock down someone for trying their own thing and possibly being good at it. Stay within your box.

thanks for the replies, and I do have a good understanding of engines, my father has ran a garage for 32 years and he has taught me how to rebuild engines, however I am completely new to turbos and tuning. so when you say base maps i'm assuming you mean chip the ecu and download the fuel maps to it? and can suggest some good resorces on this? thanks!

tunewithcrome.com, pgmfi.org, and most other imformation should be included within those two. There is some book available at like Barnes and Noble or something, look in the automotive section is all about turbo set-ups, tuning, construction, etc... If I knew the name I would let you know, but sorry I dont they usually have one copy at least. And, if your father is the owner of a garage he should have tuned some carburated V8's in the past ask him what he knows, old guys are full of valuable imformation. Hopefully that helps, good luck with the build.

thanks for the links they are very good sites, but I guess i'm just looking for something that will work without any extra hassle, and I don't even need that much HP if I can just us an FMU, cause I got the turbo for $100 and other than an FMU that's all I need to buy, I can do everything else in the shop. so just to be clear, if I use a 12:1 FMU with 6-7 PSI then that's all I would NEED right? I'm not doing any racing either, I just want the car to be a little less slugish. Thanks!

an fmu is garbage. it exponentially adds fuel. this is not a tune. you will waste fuel, lose power and risk damage to the engine and fuel system due to high rail pressure and cylinder wash out. spend the money on a tune. the tune is the only part you dont want to skimp on.

Personally I would not use an FMU, they might be good on other cars but i'm afraid with a Honda as busa4 said 'they are garbage'. Your Honda would be much better with a chipped ECU from somewhere like Xenocron Tuning: Fuel Management and DIY Tuning Resource Center for Honda and Acura Performance - Hondata, eCtune, Neptune, Crome, TurboEdit, Uberdata they are cheap enough and will come with a decent basemap. After sales help is very good too.

so if I buy a chipped ECU or chip my own, then I can just download a basemap that fit's my application and that's it right? Or do I still have to do some tuning?
I just came across this page: http://www.-------------/chipping-kit...cus-p-277.html

If I get this and get them to do a basemap for me, would that work? thanks

still will need tuning.. what you are downloading is a just a rough estimate of what your car needs

The car will run nicely (usually) on the basemap provided and can be set to suit your set-up aproximately but no two builds are exactly the same therefore some tuning will need to be done. I have just started to tune mine via a wideband O2, a datalogging cable and a moates ostrich. the map I got with the ECU from xenocron runs the car fine but it is a bit rich. I'm using the free datalogging program called Freelog and i'm using Crome free to play with the maps through a laptop. The Moates Ostrich does away with the need for a chip burner and chip and has the advantage of being able to upload map changes on the fly so you can hear and feel the changes as they happen.
You need to be able to analyse the exhaust gases to tune properly hence the wideband O2 sensor, unless you have access to lots of dyno time (who would have gas testing equipment). These are the forgotten costs of turbocharging but if you're willing to have a stab at it then you'll save lots of money in the long run and will have a much better tuned car than you could get just sitting on the dyno, as dyno tunes can never properly simulate real road conditions.
The ideal stoichiometric value for petrol cars is 14.7 and this can be acheived throughout the fuel table by tuning the ECU at home, just think how much fuel you'd waste with an FMU at 12.1.
Good luck

Ok, that's what i'll do, but until I get some extra cash, just to clarify the car should run fine with the basemap they give me. and with this setup I should be able to get around 8 PSI safely? thanks

yeah if the basemap matchs your setup it will be fine but I wouldn't go nuts and bring it to a track or beat on it untill its tuned

yeah, I'll take it easy on it, besides I don't really have any plans to do any racing anyway, I just wanted to have a car that you don't have to have it to the rug to hold your speed with 4 people in the car, lol.
anyway, thanks for all the help, much appreciated.

Yep, it's what I did and had no issues other than it being a bit rich, but being rich is safer than going lean. I'm running a shade over 9psi on stock everything. I think though that with 8psi you'll be looking at a good deal more than your 170bhp target. more like a realistic 200+
