I am sort of new to hondas as I am a nissan guy. Just got a 95 gsr and im piecing together a small turbo set up. Ill most likley be running dsm 450cc injectors and a bigger fuel pump and fpr to be safe. I only want to run around 7psi. So my question is what should I do about tuning, could I get away with just a safc, and whats different about the hondatas I see s200's and s300's. What are the hondatas capable of, are they just a base map to tune on? And witch hondata should I get. Been searching all night and still am.

 

I'd stay away from the sfac. I've got a budget turbo kit on my car and I'm using crome. So far so good. It's free.

And to tune with I went with a zeitronix wideband and map sensor to datalog my afr and boost. It also logs TPS, Lamda, RPM and a 5V user input of your choice.

That's all I seem to need to tune my car.

 

were do u get crome

 

forget crome and go with ectune.

Nothing wrong with Hondata though..

crome is the new uberdata.

correct. nothing wrong with hondata.....but i used uberdata up until ectune was released and i would choose UD over crome.

i made 420whp on UD

just to bad there is no more support for UD anymore and it is outdated.

 

so for ectune I just buy the moates ostrich and the hulog and im good to go? How does it hook up and would the shops have the programs needed to tune it?

 

Crome is still GREAT imo. i use Crome Gold to tune all my customers cars and i have had zero issues with it. You cant beat the price, but i wish there was more support for it

 

Only software we recommend: Hondata, Neptune, eCtune.
Crome works but has it's issues. If you do enough research you will find threads discussing them.

I got crome from here: http://forum.pgmfi.org/index.php

The only reason I mentioned for you to use crome, isn't because crome is the best engine management software out there. But you said you're putting together a small turbo kit. So I'm assuming nothing fancy and just something that you can edit your ecu with.

I think crome will accomplish your goals. Plus, like I said it's free. I used to use uberdata, but like someone else said, it's outdated and there isn't any more support for it since the creator stopped developing it.

I would have wanted to run with hondata instead of crome. But I've just got a simple daily driven stock 9 psi ls turbo. Nothing fancy, but it's solid, reliable and functional. And I feel crome has accomplished those goals of mine.

So once you define your project goals then you can pick your parts that will meet those requirements.

When I was learning about turbo's on my car, I know that I didn't want to invest a lot of money into the learning process. So I went with what was cheapest, yet still functional and reliable. My first project I went to the junk yard and pulled pipes, hoses, injectors, ecu's, resistor boxes, vac lines, turbos, etc. Then I learned how to test these junk yard parts for functionality. Then I installed them and learned what works and what doesn't. I think my first turbo kit I spent about $600 to build.

So we all could go on all day if hondata is better than crome or if ectune is better than uberdata. But what really matters is what works best for you.

Good luck!

 

crome sounds exactly like what im going for, im just going for prly around 7 or 8 psi on my gsr and keep stock internals, just want some more power for my daily driver. I am sort of confused on how you set these systems up though, for my old nissan i went turbo, 200sx, but for my ecu i just sent it into jwt and they tuned it for me and sent it back and i just pluged it in and drove. cost around 300 for them to tune it, all i had to do was tell them my maf size injector size and what size turbo i was running

 

i've read the issues with crome, mainly reguarding the timing. But appearantly crome gold and the timing script for regualr crome has fixed this issue

 

Well, you'll need a wideband 02 sensor, so that you can tune your car. Or so you can take it to a shop to tune it for you. Every car is different, so sending in your ecu and having them tune an ecu without the car is rather wasteful. You spend all your time and money to turbo your car...you don't want to half *** the most important part. Which is getting every hp out of your system with a good tune.

You'll need to make some changed to your ecu so that you can edit the bins and add a new one. I made these changes to my car years ago, so I'm not familiar with exactly is needed. But I'm sure you can search around and find it.

once you edit your ecu so you can use rom's in it, then you can use crome to create those bin's for your car.

And once you create those bins, then you can burn them to a prom chip with a chip burner, like burn1.

Then just put that chip into the ecu that you edited and you're good to go....straight to get it tuned on a dyno with a wideband.

 

im all very confused by these methods of tuning
