Hello Guys,

New to this site.

Well, story is I picked up a CRX si with a JRSC on the car. The car has stock motor, but I noticed that the timing was pulled forward, towards the front of the car, instead of in the middle area, where the distributor usually lines up flush.

Anyway, has anyone had their JRSC tuned? Does it even need tuning?

Any local shops in San Diego that can tune it?

Car seems slow for some reason....I will check the plugs and do the oil tomorrow.

thanks


Some pics of the Rex:

How do you make a thread about the JRSC and not post anypics?! haha.

Car looks great dude!! It looks like it was well maintained and someone baby'd it.

I heard you arent supposed to tune the JRSC, just adjust adjust the timing. Do you know what kinda clutch the car has? It will need one able to withstand teh extra torque from the motor or else itll just slip.

Looks like the base timing was retarded at the distributor as a bandaid fix AKA ghetto rig.

cheap solution:

Chip pm6 ecu. get chip burner (moates BURN units are nice). Download turbo edit.
Get a tune, find someone who tunes turbo edit.
You now have precise control over the ign timing.

better solution:

convert to obd1, run a p06 ecu with Hondata s300/eCtune/neptune/whichever you choose.
get a tune. this obd1 software is much more powerful than the obd0 rom editors.

also, what plugs are you running? you need to be running colder than stock, 7s or 6s

looks like a beautiful CRX, goodluck.

Thanks for the responses guys....

I will post a pic of the engine bay tomorrow when light is out.

The motor and tranny are stock...There is an aftermarket clutch in the car, but I'm not certain to what kind.

I believe the SC is running stock boost (stock pulley).

No chipped ECU's or piggy backs.

What will happen if I readjust the timing to where it should be?

I will pull the plugs tomorrow to see what plugs are in it.

thx for the help guys

the timing may be too advanced in boost, potentially a detonation hazard. boom, broken ringland.

the jrsc is cramming all that boost in there without any cooling.
you already have the high intake air temps against you in the detonation hazard department.
