Hello honda tech i'v had this little problem on my integra for a while and its stopping me from doing a retune my car is a 91 integra da9 b20b vtec on boost its tuned on chrome using a p28 on 2lbs tuner had to stop cause he wanted me to fix my check engine light before he kept tuning so iv read up forms and all and none seem to help me on how to find the code from the light.when i start my car it stays on all the time and never goes away,also my car tends to idle a bit up and down from time to time but idles fine when it wants too, whats the best way to check this code iv tried a few times but failed maybe someone could help, it would be really appreciated thank you, mike

 

fixed.

 

On 2lbs? What's the point of even having a turbocharger then? lol.

Are you asking how to find out what code it is throwing?

 

naw i had to fix the check engine light so i could retune i had it on 4 lbs but fixed a vac leak and now its at around 2 or 3lbs going to retune at around 8 or 9lbs to get 300hp

 

A solid CEL would indicate a bad ECU/ECM. 94
