Hondata

2008 Honda Civic Si, Injen SRI, everything else stock.


Hondata says "dyno tuning recommended" ... but is it possible to safely (taking small steps/making small changes) to tune my civic si using datalogging?

I ordered the FlshPro for that reason... but I didn't find any sections in the help for 'non-dyno tuning recommendations'.

Can someone make a list of where to start tuning?

For example: 1. start with fuel tuning... but when it comes to locking the cams at the 0,15,30,40,50... do I lock it and do a datalog, then come back and do analysis and changes?

My question is, what am I able to tune safely without a dyno? (a simple list will help immensely)

Without a dyno you will not be able to acurately measure the power changes.

so there's nothing I could do?

Can I buy something to plug in and check power of the changes I made?

thanks. that helps.

Without a dyno you will not be able to accurately retune the intake cams. You have to be a very experienced tuner to fully street tune the car.

Exactly right. I think you can vouch for my tuning from the work of mine you've seen. My calibration was on a dyno and Aaron's was street tuned. A quality street tune can net you 90% of a dyno tune with ease. There are examples where aftermarket internal parts come into play that are a different story, and following standard tuning procedures doesnt bring the same results. Stock internals are easy to work with because of the vast use.
