I HAVE A CRX SI WITH A GSR AND IT TURNS ON AND RUNS BUT IT WONT LET ME REV NO MORE THEN 2RPM I NEED HELP ANY IDEAS WHAT IT CAN BE

 

First - TURN OFF CAPS!!!!

Second - use proper English as it will get you much further in this forum.

Third - is there a check engine light and could you give more detail as to what the car is doing?

 

yes there is a check engine light...when i turn the car on and try to rev it..it wont let me go more then 2rpm.. it kinda does a two step

 

What ecu are you using? If possible, can you get the error code? Is all of your sensors plugged in, and plugged into the right location?

 

...with the error code we can help a bit more.

 

ill check right now but yea all the sensors are plugged in and im using a p28 i also have a p72 i can use

 

wow at the username........

Did you swap it? Did this just start happening? Did you buy it this way?

Little history for us will help.

 

i did swap it and this just started happening it was running good

 

well still need help the ecu code i cant see it has no light but i am using a automatic p28 ecu do u think thats the problem

 

common people i no someone has to no or give me some thing to check for please i need my car running

 

being impatient and answering every hour will not get you more useful responses.

 

i have an 89 crx si with a jdm gsr in it .. i am having some problems with it. ok this is whats happening... i am running an automatic p28 i also have the clipover to obd1 i turn it on and it works fine but it just wont let me rev over 2rpm.. it kind of 2 steps and back fires. i also have the check engine light on. i just dont no what to look for i checked basically everything so any ideas please ......

 

Swap to your other ecu.

 

tried but it makes it worse

why make another thread?

 

wanted to explain myself more sorry if its bugging u

 

its not really bugging me but with your childish all caps lock name and that past thread i just want to tell you quite bluntly that people will not really want to help you.

 

The automatic ecu could be your problem, however I think that there is something more to it. Did you check your timing after you did the swap? Sparkplug wires in the correct firing order? You sure you didn't mix up the TPS and MAP sensor plugs since they are close together.

 

yes im sure but will double check i switch the ecu to the p72 and its worst but yea checked timing and it good thanks for ur help

 

What CODE is it showing you?

 

The p28 ecu is meant for the sohc D16Z6, commonly used for 95 ex's and Del Sol. The GSR is a DOHC motor, so if you are running an ecu that is only meant to adjust and moderate the cam timing for one cam shaft, you will get some issues when you use it on an engine with dual overhead cams. try a p72, that is a B18C1 (GSR) series ecu. Using the wrong ecu can really mess up your motor, so switch it out asap.

 

I SWITCHED IT BUT IT MAKES IT WORST

 

DONT NO HOW TO FIND OUT THE CODE HAS NO LIGHT ON THE ECU

 

Please stop with the caps.

Just ask the question dont dance around it, I'm guessing you need to know how to check the CEL code.

First you need to jump the service connector (stick a u shaped wire in the plug to connect the curcuit), its the green plug neer the ECU.
Once you do this the CEL on the cluster should start to flash the code.

Reference the code here https://honda-tech.com/forums/honda-civic-del-sol-1992-2000-1/how-pull-cel-d4-srs-abs-codes-code-lists-1901557/

 

nice info but i have a crx and cant find that plug its shows u but for 92-95 and 96-00
