WTF is going on? **update**
 

So the other day I was reading a write up by Chris about crome and getting started converting maps and making a basemap. Now that I'm wanting to find it again, I can't find it on his site or pgmfi. WTF?

Re: Hidden xenocron write up.
 

See link below. I hope it is what you are looking for.

Re: Hidden xenocron write up.
 

Well god damn. You found it. I was in the "install" section of his website but it said I needed a password. This ecu ----........ :'( Thanks.

Re: Hidden xenocron write up.
 

I've looked at this ecu ---- plenty of times, but today I try to put it to use. There will be a real tuner along for the ride. All I need to do now is figure out how I can get FTL on crome. Dang, I almost feel smarter. :P

Re: Hidden xenocron write up.
 

Look for the AddExtraFeatures script

Re: Hidden xenocron write up.
 

working on it now. ;)

Re: Hidden xenocron write up.
 

Ok, after I download "add extra features" and all that I go to plugins>enhancements>add extra features and it gives me a page error trying to connect to some web page.

Re: Hidden xenocron write up.
 

yippee, I got it to work. Now lets see how it does in the car. :l

Re: Hidden xenocron write up.
 

:l i did it (launch control and so..) and work fine.. ;D


UD has more options about this kind of things..

Re: Hidden xenocron write up.
 

So the shop we're doing this with has a pocket programmer 2 from an old hondata kit they bought, and we don't have the driver disk for it. One thing to the next.

Re: Hidden xenocron write up.
 

I have the software at home.

Re: Hidden xenocron write up.
 

Re: Hidden xenocron write up.
 

We have one at the shop. I can burn the drivers if those listed above wn't work.

Re: Hidden xenocron write up.
 

Ugh, so we were out until 130 last night trying to get this fucken car running. Everything is good, until 4-4.5k rpm. It sputters like it's misfiring. But if we put the stock ecu (P13) it revs all the way out.

JDM H22 in EG running P13 with t3/t4, 450cc, 7psi.

We ran both the stock USDM and H22 maps converted to the P30 rom? just like xenocron's write up says. We fucked with the timing and afr's until it would run really good until 4-4.5rpm. Even when it started stuttering, the air/fuel was good. I thought it would be an ignition problem, but why would the stock computer let him rev it out (with 450's too ???)

Anyone?

EDIT: Stealthmode had an experienced tuner and a dyno jet, so it's not my fault. :D

Re: WTF is going on? **update**
 

It's never anyone's fault, Steve, it's just work sorting the car. Like you said, you were out until 1:30 last night actually doing something instead of bitching about how you're too lazy to figure it out on message forums. You've got our help.

AFRs "looking good" while the car is breaking up doesn't make a lot of sense. If it's not burning the fuel then you get a false lean reading, since the O2 sensor picks up unburnt oxygen.

Crome is *very* stable compared to UD, but sometimes Crome's script engine compiles the code fucked up and it (usually) dead CELs or (rarely) just acts wierd like you are experiencing.

I'm going to up Stevo's 880cc H22 .bin to xenocron's site. You can recurve for 450 under fuel tools- keep in mind the recurve should be 240/450 not 450/880 FTW, that's a common mistake; fuel maps with FVFT are always in referrence to stock 240cc unless you're doing something wierd as ----.

If my .bin looks like gibberish, I'm more than happy to send you my .rar'd Crome directory which is already configured with all my favorite plugins. Let me know.

Re: WTF is going on? **update**
 

FTL? What did you set that at? and is it off for the tunning?

4.5K is too high for limp. Getting any CEL's?

Re: WTF is going on? **update**
 

sent it to me too ;) ill appreciate it!

Re: WTF is going on? **update**
 

Maybe some better insight will help.

H22A with P13 ecu runs fine. It does have a code 41 (heated 02), but we disabled it on crome and the one map we ran from uber.

We have a manual P06 chipped with added vtec. The car has a sold cel and can't be checked, but making map changes we get the car to run up to 4.5rpm, where it sounds like ignition breakup or a rev limiter.

Stock P13 ecu with afc we ran well to 200+ with only the heated 02 cel (it's not even hooked up).

Should I be looking at the ecu, or should I be looking at the files? Multiple crome maps ran. A basemap that we changed a couple times with no luck, some of the "tuned" maps out of the library, and finally a "TunedH22" map from the uber library that we didn't even open. Just download and burn.

Asian pusssy smells like catfish.

Re: WTF is going on? **update**
 

You have a solid CEL. You need to now figure out if its ECU, ROM or chip related. The best way to do this is open a p30 rom in Crome, scale the fuel map down for your larger injectors(add more fuel in the idle region), set it in debug mode, and burn the ROM. Key on, check if the CEL is still there. If it is still there(and assuming you arent a complete idiot), then you know the problem is not ROM(meaning the file) related. Now you can move on to checking if the chip is being burnt correctly. The easiest way to do this is put the chip in your chip burner, read the chip, and then open it in Crome. If it opens okay, then most likely it burnt okay. So if both of those work, then the ECUwas chipped badly.

Re: WTF is going on? **update**
 

I guess the biggest problem with this car is the wiring. It's the jdm H22A engine with the matching P13 ecu, all tied together with the stock 93 dx harness (and a couple hard wires). Would it be a definate ecu issue if it's a solid cel with the crome ecu, and a "checkable" cel with the stock P13? I thought so, but then again all of our map changes are working correctly.

Maybe we'll try a different ecu and see if that helps. Oh, and is the P13 chipable? ???

Re: WTF is going on? **update**
 

Try advancing the timing a few degrees where it starts to misfire. We had the same problem with my buddy's civic. AFR's where fine but it would sputter and misfire. Advanced the timing a couple degrees and it fixed it. Try it and let us know what happens.

Re: WTF is going on? **update**
 

solid cel=bad burn or bad chipping job


codes=bad sensors/bad wiring

Re: WTF is going on? **update**
 

It starts breaking up about 4500. Is that where you have vtec set? probably not but it could be a problem with the vtec conversion.

Um it could be the scaling for the map sensor to. If your using a gm sensor. If so put the stock one back on and try it. But probably not because if that were the case it would have normal cel not solid.

Re: WTF is going on? **update**
 

VTEC is set to 5200-5400, IIRC.

Re: WTF is going on? **update**
 

I don't know what IIRC is, but we're going to chip the original P13 as per my JD consultation.

Re: WTF is going on? **update**
 

Sweet. Is chipping a p13 the same procedure as the p06?

Re: WTF is going on? **update**
 

He has a solid CEL. Thats why he can't rev without misfiring at 4500rpm. Why are you guys making this complicated? OBD1 doesn't have seperate limp mode tables from what I've seen. They just take the stock fuel maps and multiply them by some number and it makes the car run crazy rich. Thats why he can edit the fuel map and make it run better. Just fix the solid cel and tune the car. Tuning a car with any CEL is a bad idea.

Re: WTF is going on? **update**
 

Inqy, you are an idiot. Disregard everything this guy says - he's bright enough to make it sound good, but obviously lacks all the cards AND enough experience to have informed perspective.

There is a back up MCU that contains preset tables that allow you to run off only TPS and TDC sensor. This is covered in basic ECU FAQ @ pgmfi.org, there is no excuse for you looking anywhere else for Honduh ECU information, and there is no excuse for not covering your basics. Spitting made up ---- out of your ass is no way to win the adoration of 16-17 year old boys. ::)

Furthermore, CEL 0 = lowered revlimit aka crisp rhythmic fuel cut. Misc ignition breakup causing engine to run raggedly is not lowered revlimit/fuel cut.

Stealthnigga can manipulate AFRs = ECU is working on some level. Solid CEL in this case = misc wiring or code fuckage, zero problem with socketing.

Re: WTF is going on? **update**
 

well jd makes sense that it could be map issue because he can change the afr,s( i think its just in his head) but
when you ---- up a chip job you can only rev it to 4.5k. if it works with the p13 and afc then the wiring cant be bad.

i say its a bad chip job just because steve sucks at ecu ----.

Re: WTF is going on? **update**
 

Jospeh, explain how with Crome, any time it throws a lovely limp mode my car won't even bother to crank over but Uberdata with limp mode would always crank over? It couldn't have anything to do with the fact that Uberdata actually edited the fuel table primarily and Crome just uses a multiplier as a the primary and the fuel table as a fine tuning? Go test this out and prove me wrong, because based on my experience, I'm sticking with the ECU absolutely references the fuel table on the ROM during limp mode.

As for the solid cel, if the p13 ECU runs clear with only an O2 cel, and I can't think of one reason why the wiring would need to be changed to run a civic/integra ECU. I'm still going with my list of things. Chip, rom, ECU. I'd go out on a limb and say 95% thats the problem and I see no reason why it would be any different on this occasion.

BTW: Pgmfi's wiki is horrible as far as all things ROM related. Sooo out of date. If you bother to compare the information in there to what is used now, I'd say there is enough things that are invalid to make most people second guess using it as a resource. If anything use the commented out ASM files as your reference.

Re: WTF is going on? **update**
 

That's not limp mode. It's code glitch that doesn't send an error to boot up limp mode.

Remove your MCU entirely, and then see how the ECU behaves.


You don't think the EGR lift sensor and solenoid have some impact? 88-89 HF are not true OBD0 MPFI plug and play for just this reason, despite interweb rumor. I've been through two Preludes now, one had similar problems but it was a couple years back + I don't remember. I get a chance to ---- with a third tomorrow that does not like it's chipped ECU, and I'll get a crash course then.

Yeah, some of us got tired of cleaning up crap after people. The ignition tuning wiki entry makes me shake in anger.

Re: WTF is going on? **update**
 

Can a p13 even run on p30 code

Re: WTF is going on? **update**
 

Crome offers partial P13 support. johncui has a hard on for P13 code, says it's structured more like a race-oriented ECU.

Re: WTF is going on? **update**
 

Guess Ill go try to open some of my all motor proggies I got for the p13 ecu awhile back

Re: WTF is going on? **update**
 

The fuel maps will make you giggle.

Re: WTF is going on? **update**
 

We're going to try uberdata today. I'm still learning Crome.

Re: WTF is going on? **update**
 

Ill stick with p30 code

Re: WTF is going on? **update**
 

can i ask who's car you are speaking of?? i didn't know steve actually worked on cars, just invited people over to work for him :y j/k
