just got my 94 hatch running with d16z6 turbo. have hondata w/ a start up program. when i started it i have had a check engine light since. it is not tuned yet.. but i am tring to figure out if the problem i am having is the hondata, and will go away when tuned, or if it is a real problem with the injectors or something.

problem: any thorottle pressure... when it hits 2psi it is like fuel cut off... car jerks and thats it. doesnt stall or anything.. and in neutral or in gear, w/o boosting... rev the car to 4k rpm and it is like a rev limiter. wont pass it. but the car doesnt even have to be pushing any boost. and it was running a little lean. but it also does the 4k thing when it is rich or normal when first started.

i am not drving the car around. just tring to get everything straight before i go tune and find out i have some problem with my injectors or something.

by the way. i am running 2nd gen. dsm 450's with a resistor pck i got from sonny. people please help me get this figured out.

can i just tune it and everything will work, or do i have a problem? thanks

 

the rev limit at 4k is probably a launch control. try going over 10 mph then rev it to see if it goes past 4k rpm.

Most likely your car is in limp mode because 4k is usually where the car will cutoff. Reset your hondata launch limiter and what not. Check to make sure your communication wire going from the ECU to hondata is connected properly and also the button and clutch connections as well.

If worse comes to worse, you might just hafta burn another ROM or you might have a real CEL somewhere on the car. Check for codes if none of the above works.

no, it does it at any speed. in gear, out of gear.. whatever. and i dont have a launch limiter in my hondata. i only got s100 w/ boost. the only think i can think of is that it is doing it b/c it is leaned out? i dont know what else would make it not rev past 4k?

 

You need to first see if the s100 system has the light blinking or steady. If the light is blinking you are experiencing "limp" mode. This can be caused by many things, refer to Hondata's website for the list of symptoms. If the light is steady with no blinking, then your map is terrible. You might have had the map created for larger injectors than you are using.

 

where do i find a blinking light at? this is in a obd-1 p28. thanks

 

The light is on the front of the blue interface box. If it is blinking, that is an indication that the program in the chip is bad.

Sonny

 

He doesn't have the interface box (unless Hondata is lying about their s100 system).

 

umm.... all of my hondata stuff is enclosed in the ecu? am i supposed to take the ecu apart? i bought mine from collin at " RPM NYC" ( ekb18c ). he said it might just be a loose connection where the chip connects to the ecu. said something about sending me another chip to try?

 

There's a red LED on the blue circuit board that plugs into the 4 pin connector. yeah, you have to take the cover off the ecu to see the red light blink or not...

 

ok. take the cover off ecu. urn key to on position and watch for blinking LED. correct. any certain sequence it will flash like a code if it is a problem, or just regular flashing if there is a problem?
and if there is no flashing then its fine correct. thanks

 

alright, just went to check my check engine code... or CEL code. it didnt flash any codes when i connected my little wires, just stayed on solid. so i am taking that as a confirmation that my hondata is causing the check engine light in the dash. i will go out and take the cover off of the ecu in just a second.

 

I think it's because the map didn't get fully burned onto the chip or the chip is bad. I wil be sending you a new chip with a base map loaded onto it and I will vertify that it works.

However you said that you were going to get it tuned on Wednesday. If you are going to get it tuned on wednesday then the tuner will probaly start from scratch to create a map for you and then start tuning from there. He probably wont use any start up maps because most tuners don't like using other peopele's maps to tune thier cars.

Give me a call. I PM'edyouu my cell phone number.

 

ok, well if my chip is just bad.... then the new one you send me will need a base map so i can still drive it out there. but hopefully it will just be a loose connection that the tuner (also hondata dealer and installer) can fix for me to save the time and trouble.

if i check for that flashing LED. if it is flahing.. that means the chip is bad? or just the connection.

 

check your sotire it happened to me yesterday and also check out the manual it tells you everything

what manual... and what is "sotire"?

i know for sure it has to be something with the hondata now, cuz the car wasnt throwing any codes...

 

In my own experience...and I was helped by this board.

I had the exact problem....4k rev limit...2psi boost cut(more like 1psi for me), any gear, any speed.

My problem was a bad connection with the interface box....but I just read you do not have one.

EDIT....I have stage 2B.

Also with the CEL...it was on the whole time and when I put the jumper, the CEL just stayed on.

When I got a good connector, car ran well and no CEL.

Hope that helps.

 

Sounds to me like the map is bad. Either the knock sensor was not disabled, boost not enabled or set up, or the boost cut was set really low, which on a base map to get tot he tuner is a good idea.

 

well if the map is just bad.... thats no big deal right... cuz the tuner will fix all of that anyway.?

Yes.

 

Also make sure that J12 has been cut in the ECU. with the cover off you can check htis and at the same time, with the car running make sure that the light on the s100 is solid and not flashing.
