CEL for ELD pissing me off

Well, pgmfi is basically worthless, i’ve asked about this problem on two separate occasions…got a good amount of views but not one response.

I have a 92 Integra LS/vtec with a b18c1 head. I’m chipped on a pr4 with the vtec conversion using Crome. The car runs fine and vtec kicks in…but when I’m around 90mph or leave the car in high revs for a while I get a cel. I checked it and I’m getting a code 20 and 22. Electronic Load Detector and Vtec malfunction. Now the thing is I disabled the ELD, so I don’t see why it’s still reading it, the g2 integras don’t have the eld. I tried reburning it a few times just to make sure since I know that sometimes the programs don’t always get burned correctly…but I’m still getting the same CEL codes.

Problems I’m thinking it could be:

-Crome isn’t disabling the ELD and needs to be a certain setting for it to work with my pr4 ecu…

-Not enough Oil…I don’t know how much a b18c1 needs a far as oil, I put what my manual said for the b17, too much oil is not a good thing so I didn’t want to go with anymore than I should. Maybe it’s enough pressure at the lower speeds but not at higher speeds, but I would think it would have more to do with the rpms for the pressure. But still doesn’t explain it reading the disabled ELD code

-I wired up a Vtec light, i’m wondering if it’s taking away some of the current to the solinoid making it not function correctly since all the power is going to keeping the motor up…I don’t have a resistor since the tutorial I used said you didn’t need one, but i’m thinking it might, or I’m going to have to take it out. But again reading a disabled eld code

I tried reburning it again today but it’s still stuck on giving me the same codes. And it’s on a completely stock p72 basemap. All I did was disable knock sensor and eld. I know some people have been saying on other threads to disable the o2 heater sensor, which really sounds like a stupid thing to do.

I had the same code for my old ls/vtec. But the reason why was because i used a obd0 to 0bd1 conversion and had a obd0 §§§§§. Fixed it with a stock pr3 0bd0 ecu. I would check your wires and redo them

But, I’m using a obd1 pr4 with an obd1 94 GSR head, and my car being 92 is originally obd1. I checked the wiring the other day, everything has been plugged into the right sockets. Vtec does work, it just gives me a cel at higher speeds.

bump, still need help

try taking the light off. that should work.

So you do think it’s the vtec light? I’ll give it a try and see what happens

I read on another forum that when you get rid of the code 22, the ELD code will also go away. I can’t confirm that. The VTEC pressure switch needs 50 psi at the head or it triggers the code. Its not quantity unless there is so little oil the pressure is gone. If your VTEC is working but you are getting the code, you can put a jumper between the VTEC solenoid wire from the ECU and the VTEC pressure switch wire to the ECU. In other words a jumper wire between the wires going to D6 and A4 on the ECU. If your VTEC is not working, then you need to check out the oil pressure. The only way to do that when the car is stationary is to hook up an oil pressure gauge to the inspection hole on the head. Its on the exhaust side at the distributor end of the head. You then run the engine to about 4-5k RPMs and apply voltage to the VTEC solenoid lead after disconnecting it. You can’t just run up the engine because the ECU won’t trigger VTEC is the car is not moving. By applying 12 volts to the solenoid, you are manually engaging VTEC. Examine the gauge and see if you get 50 psi or more.
