Hello everyone I recently picked up an Ek Hatchback that has a y8/y7 minime with a fully built head, and fuel system. It's tuned on chrome and really is in need to get some stuff smoothed out.

I'm kinda unfamiliar with the way chrome works. Can I edit the existing map with the software and wideband or do I need a burner as well? I just need to make adjustments to the fuel map.

I apologize for the nube questions but all of my tuning has been done with s300.

 

Would anybody be interested in sharing their all motor mini me maps?

 

Attached is the link to the crome manual , worth reading. I would open up the ecu you have to see what it has . Then you can see what you need.


I would move to Honda tuning suite, both will do the trick .

details on what is needed also is on the site

 

I'll look tomorrow but he person I got it from said it's on chrome. So I need the ostrich to plug the chip into it, whiles it's plugged into the ecu and go from there. So I can get the ostrich and just use HTS as the software?

 

Both use exactly same method. You can read the map you have in crome and convert to HTS , or keep on using crome. I used crome , ectune , neptune, hondata S300 and HTS . All great for what they are. For the cost of free , it's hard to not use HTS now a days.

What is required to tune with Crome?

• OBD1 92-95 Honda Civic/Del Sol or OBD1 92-95 Integra ECU that is socketed to accept a 28-pin chip.
• Laptop computer with Windows operating system and at least 1 available USB port.
• A chip programming device - we use and recommend the Moates BURN2.
• A chip to program/use. We use and recommend SST chips.

What is recommended to tune with Crome?

•  
  • In addition to the required items above -

• Crome Pro license - required if you wish to datalog using Crome.
• Moates Hulog datalogger - allows datalogging sensors, etc. while tuning.
• Moates Ostrich - allows uploading tune changes to the ECU in real-time.
• Wideband oxygen sensor - allows viewing/datalogging air/fuel ratios so that you can make the appropriate fueling changes.

I find if you are starting up, HAmotorsports tech library section is great , and if you need any new parts, worth buying from them .

I appreciate the feedback, most of the links to the parts in the reply are 404'd.

So I need a data logger, the ostrich, wideband, a chip and the burner. Can I reuse the chip in it?

If it's a legitimate chip, then yes it can be reflashed many times over.

So I have just decided to go to use my Hondata s300 for the civic until my gsr swap is built. My wideband should be here in a few days. Is anybody willing to share a map with me so I have a good base to start with.

It's got a BC stage 2 drop in cam, aem cam gear,springs, retainers, valves, seats, guide lines from skunk2 and ferria.skunk2 intake manifold, 70mm throttlebody, whale ***** intake, fic 525 injectors, aem rail, regulator, and pressure gauge, 3 bar map sensor, walbro 255, stage 2 clutch and a flywheel I do not know the weight,1329 header, and hks exhaust.

It pulls like a geo metro and buran's ALOT of gas. I've never tuned a all motor sohc so I'm not really sure on how to set ignition.

 

Looks like a nice setup, If you have the TB and injectors from your GSR , migth be easier to get you started and drive smoother.

From the sounds, the map is probably not scaled for the fic 525cc injectors you have.

If I recal there is a D16 base map, take this map, update injectors to 525cc . Everything else should work, then before starting car, go to injectors setting , turn them off . Then go to timming and lock timing to 16 degrees. Take a timing gun and insure the your timing is correct as car is cranked. If good now turn back on injectors and "unlock" timing.

car should start , now set your base fuel pressure to 42 psi ( or what ever the injectors paper work say to start at ) . ( PS stock injectors will do just fine if you have them kicking around and are good and clean, same with fuel pump the walbro is over kill, a good stock integra pump will do the trick ) .

Now the car should start and drive , I would bring to a tuner to get it sorted nicely. If not you can try tuning none vtec tables to 6,000 rpm and get the cruise where you like it so it sips fuel during cruising . Then start tuning the vtec fuel map. I wouldnt touch too much of the ignition map if its your first car you are tuning.

 

Not the first car I've tuned just the first in a long long time. I just had fic send me the dead times for the injectors so as soon as the wideband gets in I'ma check it out and go.

Quick quest as well. The guy installed all of the parts and the aem cam gear is at zero. That's correct as it's drop in?

 

yes, looks like zero is the best place to start for that cam

BC Cam Stage 2

 

My brother thank you for the info and quick response. My timing is dead on I'm just waiting for my wideband and going from there. I've found a few good y8 maps to be able to start with as a good base. From my understanding people keep their y8 maps close to the chest. It's weird.

 

Thanks for the helpful tips, and especially for the PDF manual. I’ve been looking for this info. Speaking of PDFs, I recently came across a free online converter https://pdffly.com/ that’s just incredibly easy to use. It even has a built-in PDF translation feature. So I finally managed to translate one of my manuals from German.
