Here's the Enigne
82mm (1mm over bore) GSR
LS Crank
LS Rods
GSR Head
82mm USDM ITR Pistons
JDM GSR Cams
Skunk 2 Pro-series Intake Manifold
I have 440cc RC's that i was hoping to use

So the build is not too crazy or too far off of stock.

There is a very experienced/qualified tuner in town and would be able to give me a very good base map and do the sensor deletes and have it not throw codes and what not.

But Here's the question will that be plenty good or really how much better will the dyno tune and custom fuel maps be for this build. or is that over kill?

or run gsr ecu with stock injectors.

So the way i can see it those are my 3 options.

So share your thoughts or experiences with me on my next course of action i want to do whats best but not spend money that i dont need to.

thanks team.

 

tune it. a base map is just that, a base to start from. you should NEVER drive a car on a basemap, except straight to the tuner.

 

This is true. With bigger injectors, fuel multipliers will only get you so close. Plus you aren't running a stock GSR at all. Definitely get it tuned. Even a good street tune would be nice. Dyno tuning will net you more gains, from what I've heard. Timing is where you get a lot of the power in a NA build, right?

 

So except for the .1 liter difference in displacement it's basically an LS-VTEC set up with bolt ons. if i ran stock injectors would the stock ecu cut it. or would a base map do better.

I understand the importance of the tune and what that will do. but im starting to think my set up might just be simple enough that a tune wouldn't be necessary unless i want to run those bigger injectors.

 

So what do you want to hear?

Seems like you want to do anything not to require a tune... So why bother modifying your engine. Most of the power gain will be found in the tune, no matter how small the mods.

Base maps are not the most reliable resource(PERIOD)

If all you want to do is run a stock ECU. Why not just build a stock engine and run that.

 

The initial plan was to do the dyno tune. but i want to see all angles.
What I want to hear is ALL points of view (EVERYTHING) so dont let that bother you that i want to hear everything thats out there before i do anything to my car. Im doing the research i need to plan out the best path.

Id like to know how base maps are made using the software to know how ball park they are. Because right now i dont know anything about their acuracy except that it's sufficient to take it to a tuner and do a start up procedure.

thanks for your "knowledge"

 

You want to spend good money building an engine and then don't want to do the most important thing and tune it,dude fit the STD injectors and ECU drive it straight to the tuner and get him to do a solid tune in it with your RC injectors fitted on the dyno settling the engine in.

 

Basemaps are created from experience by experienced tuners, unless you go to someone who doesn't actually have experience with tuning, but designates themselves as a tuner because they've opened the software before. That happens a lot, so choose wisely.

A basemap is just a starting base and will likely be conservative in order to help you reach a proper tuning appointment. There are no other angles to see. That's the end game. Even if it's a properly tuned calibration for someone else's setup that is similar to yours it will not produce the exact same results for you.

 

HRTuning has never steered me wrong. I bought the software somewhere around 2009 when it was the new kid on the block. Honestly spending so much time in the software and chatting with him and downloading the latest and greatest software.

These "do I need a tune" discussions are always funny, you would be surprised how De'Tuned stock cars are its funny. I think the only one pretty close to dialed in good is the S2000 tune.


Either way long story short... buy good tuning software and get a tune. If the 4 letter word "SAFC" comes into this discussion stop right now, trade your car in and buy a pedal bike.

 

This is the advice I'm going to give to every completely unreasonable question I see.

On topic, definitely tune it. It has to be tuned. It will run on a base map. Any motor will. It's not worth your time or money if you are just going to run a base map.

 

Tuning is the life of the car.. I cringe when I see people buy **** tuning software. Buy some tuning software with ***** its the most important aspect of any build..

So what if it costs ~500

 

Ehhh. I'll disagree on that one. I don't think you have to spend money on the tuning software if you are taking it to a good tuner. Everyone says Hondata is the bomb and that Neptune is great. Which I'll agree with, but you don't have to buy those if it's out of your budget. Taking it to the tuner and spending $400 for him to use Crome and tune your NA set up will be well worth the investment.

 

Crome tuned by a good operater is a very good entry level to Honda tuning and is not as bad as alot of people say it is I have tuned more cars on it than I care to remember and honestly have never had an issue that could not be fixed with a little bit of effort.

The key isn't just the software being used. It's the tuning abilities of the person using the software!

 

I am biased. I like to do everything myself, having the ability to live tune a car is where its at.

Make a change, you instantly see the reaction. None of this take a chip out program it and put it back in the socket nonsense. Its worth the extra $ for me to do this.

 

Only tuning software I know that is still chip dependent is the free version of Crome. Crome Pro ($150) has live tuning capabilities.

 

Yes, plain and simple, dyno tuning is the best bet. A good street tune can be a safe way to get the car close, as long as the tuner doesn't go overboard on timing. Using a det can or some way to detect knock would be the safe way on the street or track. I've tuned max timing at the drag strip by watching trap speeds, but I wouldn't push it that far unless the person wanted it (this was on my own car).

A live tuning solution is a great step up from chip burning. At least here, no one would mess with tuning it which is why I learned on my own. I did that mess for about 4 years before I switched to Neptune RTP/Demon and never looked back. I'm still the only guy around here who'll tune stuff with chips lol.
