GReddy TD05H-18g with FMIC @5psi
GReddy blue box FCU w/ 310cc injectors
Stock exhaust/cat...etc.
Action Stage 2KS clutch
91 Octane gas

The green line is with stock timing and the red and blue lines are with timing at 12 degrees.

The person that dyno'd my car said my car was detonating so he retarded the timing. I don't know how he got the a/f ratio since there was no sniffer used...besides the fact that I saw him clip some wires onto the spark plug wires.

I had the idea that the GReddy blue box was made to run rich...so I'm kinda lost as what to expect. I guess I'll check my plugs later tonight.

Get a decent exhaust on there! Not bad numbers though I can't see major detonation there myself? You running 1stage colder spark plugs????

 

He had no a/f sniffer and it still produced an a/f chart? He must've 'borrowed' that from another dyno plot.

The typical a/f curve with the Greddy blue box looks like this:

not bad, but it really makes me wonder about the air fuel curve with no sniffer? maybe he just put it on from another graph to try and look cool

 

yeah it looks like he selected the afrs from another dyno pull...that is how you do it in WinPEP...

 

My timing is at 12 degrees...should I go back to the stock timing since the "tuner" said I was pinging pretty bad so he retarded the timing...

Thanks for the responses.

Edit: I'm running NGK BKR7E's @ .030

1.5 deg retard per lb of boost. 5x 1.5= 8 deg. Stock timing at idle is 16 deg BTDC. Sounds like it's in the realm of OK, I wouldn't touch it.

Those numbers suck though. I ran 161 to the wheels with a NA B18C1 on stock cams. I would suggest Hondata stage 2, MSD BTM(?), or Apexi Unit- something so you could adjust the timing under boost- and get an intercooler.

 

As a dynojet owner of 4+ years, please explain to me how you do this. When you are graphing the runs, there is NO option anywhere to do this, at all. You can ONLY graph information corresponding from each run. You cannot select HP and TQ from one run, and graph a/f on a seperate chart from a seperate car without displaying his HP and TQ as well, and it would be noted on the graph he displayed above. If you'll also notice, all three runs were done on the same day, in the same hour, and the numbers on the run correspond sequentially. The dyno is real, perhaps maybe he installed the O2 in the bung?

He said he did have an intercooler, Im guessing Type 31?

Now since I have the same exact setup I wonder what im putting down. My timing is still stock, so im wondering the thump I feel sometimes is detonation or what. I guess I should get one done this week.

How much did all 3 runs cost?? Just so I have an Idea.
good numbers tho, once you get a new clutch, Hondata and a full exhaust youll improve a lot, this is what Im planning to do also!! I need $$

 

Yes, I have the Type 31 FMIC. All 3 runs cost me $35 since it was a "dyno day" deal. The thing I forgot to mention is that I do have a clutch. Action Stage 2KS...

 

Just wait to you get an exhaust!! Do you even have the stock cat in there ?? That may be the cause of the detonation.

 

Your running stock exhaust? Once you get an aftermarket exhaust + no cat, you'll free up a good 20-30 whp.

With the Greddy kit, usually at 5 psi people are making around 190-200 wheel hsp.

 

be careful with getting the boost up... I did everything by the book... ran all the wires the right way... use Mobil 1... dont get on it too much... had it at 6.5 psi and 12 degrees... then I put it at 8.5-9psi with the Profec B at 10 degrees and ran that for about a week and a half... ran a 13.5@ 105 like that... now my car sits at home... waiting for my pistons and rods to come in.. since I now have low compression on the 4th cylinder... this time Im not waisting my time.. going with Hondata or EMS... I dont quite trust manual timing changes on 99-00 Si's...

just in case you wonder.. here is the current setup...
Greddy Kit..
Type 24 Intercooler
01 Type R Cams
timing at 10 degrees
current compression: 195-200 1-3 4th 125psi

Doesn't it EVER make you wonder why the kit doesn't specify any changes in the timing?


99 Civic Si-T
under REconstruction...

Yeah, I don't plan to turn up the boost anytime soon without some sort of fuel management besides the GReddy FCU. I don't really trust the FCU for more than the stock boost settings. I do wonder why the kit doesn't specify about timing changes...

To everyone else...yeah, still running the stock exhaust and cat.

 

Bump...

So I should be okay with timing at 12 degrees? Also, I'm using 91 octane since that's what us Cali people get.
