2001 Prelude. Looking to get into basic tuning.

Hello all, I have a MT 2001 Honda Prelude, with the stock ECU, and a few mods like CAI, headers, exhaust, etc. I'm trying to figure out my best route to go to get INTO tuning. I am a programmer, and tuning is right up my alley, I just don't know where to start.

It seems for my car, I need by a OBD1->OBD2 harness, and a chipped OBDI ECU.

Basically, I have a few questions. I swapped, resoldered, and messed with ECU's before in cars, but I have never tuned one. I know the duty of an ECU and how it works, but I am clueless on how one actually "tunes" it. I am asking you guys what is the best route way to go, if I do plan on turboing my car in the future, and not having to pay for someone to tune it. (I will have access to a dyno, just not a tuner.)

What programs to use? How does it actually connect to the ECU? What hardware should I be looking into? Obviously I'm new to this, so don't tell me "Oh just get someone else to tune it" or something like that. I want to LEARN, and I have been reading, but there's not a lot of CLEAR information on this, so I'd just like straight up answers.

Re: 2001 Prelude. Looking to get into basic tuning.

Actually I just think I figured everything out. Basically you get an old ECU, that has the abillity to add that 28 pin socket to it, with a few resistors, data logger, and one more chip (Guess it depends on the ECU), then you can just by something like a Moates BURN2 chip burner or whatever, (Moates BURN2 USB EPROM Burner 5 SST27SF512 Eeproms | eBay) then you can just use Chrome or some tuning program to basically burn the chip... Then you slap the chip in the 28 pin socket and test it!.. I guess my question is, it seems like I see people tuning their ECU's WHILE on the dyno... It seems that they have a laptop in their passenger seat or whatever, and they can actually tune in real time. What are they doing?

Re: 2001 Prelude. Looking to get into basic tuning.

A good place to go to learn a lot about what you're interested in perfecting is PGMFI.org. A lot of smart guys on there. A buddy of mine recently burned a 512 using Crome in a P72 for my car an introduced me to the knowledge base there. Some pretty good reading on the subject matter.

Folks on the dyno with the laptop are using an Octopus or like device to tune live. Once the optimum parameters are achieved, they're saved to a file and then they're burned to the chip.

Re: 2001 Prelude. Looking to get into basic tuning.

I would advise against the slow and tedious way of tuning (burning Chip) and advise you to purchase a Neptune RTP unit. Neptune has great support and help videos......plus you have me.

if you want to learn how to tune, you need to use software that works very well and reacts to use as it is intended.

I would also advise to have the engine tuned by a professional so you always have a good map to resort back to when you mess up. its also a good study aid.

RTP = real time programming. meaning changes are done and noticed immediately. unlike driving, stopping, removing chip, burning chip, replacing chip...etc. very tedious and it will take forever.

Re: 2001 Prelude. Looking to get into basic tuning.

also don't just buy software based on me. you can download Neptune and Hondata for free. take a look through them and get a feeling for where everything is.

book stores will have a couple recommended books in the automotive section. one is "Electronic Fuel Injection" by Ben Strader. its the intro book into taking his classes at efi university.

another his "How to tune and use engine management systems" but I forget the author. its a white book.

both of those will give you basic understandings of ems software. you need to really hone in on the basics of EFI before you move into advanced material as it will only help you understand faster and easier.

get a strong feel for the inner workings of internal combustion and you will do fine.
for Neptune info visit HRTuning - Home Of The NepTune RTP and TunerView
- the you can get on the help forums, find the tutorial videos and the software download

Hondata is at Hondata - Honda ECU Modification and Enhancement

Both are very power software, I just have a bias towards Neptune because its very clean and easy to use. Not to mention you have the best customer support in existence.
