Hey Guys, I really hate to look stupid but here it goes, i keep reading these questions on the forums, and this chrome thing keeps comming up, I want to know what is chrome, when it deals with chipping ur ECU, any explanations would be appreciated, i have to reprogram my ECU soon so i would like to know what this is, thanks in advance

chris_si98

crome is a program that also you to run all different maps and tune it on your ecu basically. People like using crome because its free to download (except cromepro). Basically if you have an obd1 ecu and put a b-series swap in your car you can just chip your ecu and run the b-series basemap by using crome on your ecu.

im using crome... it is much smoother than uberdata. i recommend it

Crome is a rom editing program, used to modify many peramiters of your ECU.
Crome IMO is the best of the freeware tuning software.
It has the most plug-ins, is the most user-friendly, and by far the most efficient rom editing program.
Every program has its bugs/querks, but with crome you don't have to pay $600 (like hondata) or $1500 like AEM EMS or more for other standalone engine management systems. There is no real tech support for crome/uberdata/BRE/turboedit, its all based off a forum like TCC. So if you don't know what you are doing, its easy to get lost/frustrated while trying to get your car running good.
I've tuned many cars with crome and they all run as well (if not better) as cars using hondata/AEM/vafc. Its a great, cost effective solution for engine management. But if you want to do it yourself, it will get costly having to buy a laptop, wideband o2 controller, datalogging setup, chip burner, chips, and a real time programmer if you wanna make your life easy.
And great for when, like chris said, you do a swap and you need your ecu to run a different engine. Chip the ecu, burn the proper program to a chip and call it a day, no need to go spend $200+ for the right ecu.
The unfortunate thing about crome is that its only an OBD1 rom editing program, meaning you can only use it to tune obd1 ecus. Mind you converting to obd1 isn't hard and doesn't cost much, especially if you are going from obd2-obd1, all you need is a ecu conversion harness and obd1 ecu, if you go from obd0-obd1 you need an obd1 distributor, ecu conversion harness and obd1 ecu. Still much cheaper than running a full standalone system like motec/AEM EMS.
I'll end this all with....thank god for crome and of the guys like John Cui, blundar, calvin, xenocron and moates for making DIY honda ecu hacking nice and simple.

Thanks for all the answers, especially to Zeeman, and Chris_si98, i have posted alot of questions in the last yr or so and u guys keep giving great help, i had a b16 gen 2, in my 93 civic hatch, the ecu was chipped but i think the guy ripped me off, i think he just raised the rev limiter to 9200 and thats it, i just swapped a b18c , with my b16 tranny into a 92 civic hatch, ecu was already chipped, but i think i would like to change it soon, the only thing the motor has is a fuel pressure regulator and a header, and full exhaust, im just wondering, im planning on doing a couple small add ons, in ur experiences what should i do for a chip

potential add ons: bigger throttle body, manifold , pullies, just for some extra power(hopefully),, i also dont know what to set the fuel pressure regulator at right now

chris_si98

the best would be to get your ecu tuned by a program such as cromepro. Getting it tuned will maximize it's power potential, fuel economy and reliabilty. btw.. don't waste your money on pullies or a bigger tb. if anything port match your TB to your IM and get a fakedata IM gasket while your at it.

imported_Paolo

How much does that cost, and in ur opinion is the power gains worth it? What else can i do for more power, im not looking at spending too much money, maybe 1000, just to get some power, im not lookin g to build a 8 sec civic (lol), and do u know what to set the fuel pressure regulator at, i have it at 60psi right now, but i dont know if thats good or bad, and i dont want to damage anything

60psi?!?!?! good god.
Lower that **** asap. Should be 45psi.
I suggest getting a custom program made for your application (pm me for more info). A bigger t/b (or boring your stock one out 4mm) is a good upgrade, especially if you change the intake manifold....i am using a stock b16 t/b that was bored out to 64mm and an AEBS typhoon intake manifold, along with a fakedata IM gasket. I spent like $350 on all of that.
I would suggest maybe some ITR/CTR cams or a stage 1 for some more power.

the car is bogging out bad, and burn really, really , really rich, can the 60psi, be the problem

zeeman

ya man, you're killing the fuel pump too, especially if its the stock one.
A good street tune is cheap, and worth every penny, especially if you're car isn't running the best (too rich/too lean).

imported_Paolo

is it causing the idle bogging, or the runnin really rich problem, i just want to know how many different problems i have on my hands. I just did the swope this weekend, and the car is bogging like crazy at idle, but when ur driving its completely fine until u slow down, but at full throttle its fine.

chris_si98

you running rich is causing it too bog. Set your fpr to 44psi. More fuel doesn't necessarily mean more power.

imported_Paolo

i was trying to find out what to set it at for a couple of days but i got no relies, and i couldnt find anything on the internet either. So i just left it at what the other gut had it set at.

imported_Paolo

thanks zeeman and chris, i will try to ajust the fpr tommorow and see if it helps.

zeeman i hear ur the man to see about a street tune, im not going to lie i havent decided if im going to wait till after winter to do it yet , but i want to get this car running properly see whats wrong etc, see what i want to do with it, i dont want to waste ur time or anything but how is it to street tune, and how long does it take , (roughly)
