Detonation problems

scoobs187 · Post by **scoobs187** » Fri May 18, 2007 10:48 am

I wanted to know if there are any settings I have to change to the S300 to turbo at 5,000-6,000 feet of Elevation? I?m having problems boosting. Detonation problems. I started with the B16greddy calibration and I just Detonate. Boosting 3 pounds to start off. My setup is a B18C1 with Integra Type R Pistons (USDM) and skunk2 stage1 camshafts and Integra Type R transmission. Is there a better calibration for me?

i believe most of the calibrations tend to accommodate sea level. Can you post a datalog of the A/F even at idle>??

I would think about changing the pistons and cams before you start to boost this motor. The setup you have now is great for N/A but in my opinion not a good one for boosted applications.

What's the basis? You think the static compression is too high?? or do you think the intake and exhaust duration is too long??

Well for the data log I can data log but I don?t know how to down load it or watch it I tried. And for the piston and camshaft combination the compression is reduced to almost two points because of elevation. So it should be 10.83:1 at sea level but here at 5600 feet it?s like 9.03:1 or so. So I figured that on 3 pounds of boost I should not have any problems on the p72 calibration. I have been using a P72 calibration but I get full boost at 3000 rpms and I start detonating.

can you hold the wastegate open and tune the N/A maps? That way, you could see if it's the boost/vacuum that is giving you problems or if it is intrinsic to your build.

I think I figured out the data log, I?ll post one as soon as I can.

for onboard datalogging, you set up the parameters to record in the onboard datalogging section of the parameters window. i have mine set to 2000rpms and 50% throttle.

to datalog directly using the smanager software, just start the car up, hook up the ecu via usb cable, load your calibration in smanager and click the button at the top that looks like a lightning bolt. its the 7th button from the left at the top of the window. this will start hondata reading all of your sensor information so you can datalog. to begin recording the data, click the red circle button that's tight next to the lightning bolt one and click it again to stop recording. then you have to save the datalog after you finish recording by clicking datalog at the top of the window and selecting save as.

datalogging will help out a LOT when trying to troubleshoot these types of issues.

good to hear :)

i guess i was a minute late on that one.

I have some bad news, I decided to put in colder plugs in the engine and I broke one of the spark plugs. I guess Ill be taking off the head and taking it to a machine shop.

wait!!!!

how did it break??? if you sheared the threads off in the head, there is an easier way.

Grab a tap and die set with a long extension.

Then, torque the die into the inner diameter of the plugs thread that is stuck.

Then, reverse it out.

Will the tap and die set work or will I need a screw extractor? I?ll try that thanks.

i don't think a screw extractor will work because with those, you are trying to grip on something from the outside. in this case, you are trying to grip it from the inside (if i'm picturing this correctly).

can you maybe post a pic and link it?

I tried to take the plug out it did not work so I decided to pull the B18C1 out of the GSR and take off the head so I can take it to the machine shop that plug is really stuck. So im going to pull the B20 Vtec that I have in my 88 Integra and put it in the GSR, I built it for boost so that should work better and ill just put the B18C1 in the 88.

Holly shit I was just thinking of taking my car to the tuner we have in town Solid Tech in Albuquerque and their expensive well I think they are I just can?t afford the 585.00 + tax that they want for a street tune. I?m just going to have to really try to learn the hondata software.
