Im running 8psi on my D16z6 w/rc440's, Im looking for anybody with close to the same set up as I have with Hondata or some helpfull hints, I need to compare a map with mine, because my engine is detonating and nobody can seem to solve it and im no genius at fuel maps...
Thank-you

I'm sick of breaking the ceramics off spark plugs, im afraid a peice will get cought somewhere in my engine, let alone these detonation noises, eek

Tommyyy

would it help if i bumped my fuel pressure up from 38 - 42 ?

Johnyquest

since nobody is answering-- In response to your last post about your FP... TRY IT! Retard your timing a few degrees... it may help also.

did you make a map?
do you have an A/F gauge.

more info plz

Did you tune your hondata with a wideband? If not, you pretty much did guess work. What's your stock FP set at now? I think stock is around 38-42psi.

Tommyyy

Thank-you for your help guys...

I have an A/F gauge, but its not hooked up yet...

My FP is set at 38

My fuel map is pretty much guess work

Now on the retarding the timing issue, i have a timing light, but i havent used it yet. I know i set the **** at a number then click it on the timing belt and line it up with the white dot by turning the distributor, correct ? If so, what number would i set it at to knock it back a couple degrees ?

Thanx again

p.s. my detonation noises come from 4th and 5th gear , i dont know if that makes any kind of sence to you guys, or maybee i just dont hear it when im in lower gears because its just flyin...

hey tommy its steve.

Did you take a look at (my old) map on Vlad's 3B ? Hopefully you downloaded it and saved it before rewriting it. That was for a 1.8 but you could see the fuel and ignition maps. I used those same 440's @ 42psi. Compare those to what you have.

this is on the AEM site which I think they borrowed from hondata who pulled it from honda. This is again for a gsr, but it might make some sore spots stick out.

Filling up with 94 octane will help, plus you have that sunoco that has 100 unleaded 5 mins from your house. Its cheaper than replacing rods....

ps. you have to tune it on a wideband o2

Thanx Steve, im going to pull my current map from my lap top when i can get access to it later this week...

Yes, im filling up on 94 octane recently, it helped...

Steve, what plugs did you tell me to buy, i lost that paper inwhich you wrote them down for me... will they stop breaking like the ones im using now ?

p.s. ughh no, i didnt d/l your map, maybee Tim did... I was at his shop this past week and he did a couple adjustments to my fuel map but it didnt make much of a difference...

atleast i have these 440's in now


Did you get your new engine/turbo set up installed and running ?

My old map is gone if you didn't grab it. Anyways, something you can start with is retarding the ignition map 1 to 1.5 degrees across the board in the boost area.

I can't remeber the plugs exactly ngk7escp11 or something like that.

Hey All .. I just Got ordered a hondata.. and i want to run 8 psi on a d16.. can i use a pr3 ecu to do this.. .. any if will help at this point.. i have searched hondata's site.. was thinkin of calling them.. but.. anyone have any helpful info

I've had two friends with mysterious pingy conditions. Neither one had the dizzy set properly, and their timing was jacked forward. They dialed in a lot of fuel, had 12.5:1 or richer via wideband, and it still pinged until they set their timing. Set your timing, pls.

Getting your mixture *right* is hard without a wideband. Getting it a little on the rich side, and plenty safe to drive around on, is easy with the stock O2 and a few plug reading sessions. If you have 4b w/ datalogging it's pretty easy to tweak your stock fuel map to where it needs to be.

I really haven't looked at anything non-LS, but I can tell you that Hondata severely detunes the LS ignition map from stock. It's their way of providing a safe baseline to tune from. If you're getting pingies... :/

What about hot spots in the combustion chamber?

Just a question.

Tommyyy

Thanx for the help and advise fella's...

Sorry im not sure about your Hondata issue, you might want to call Hondata and ask them, or post up on there forum... I think you have to use a P28, and im pretty sure you have to have some circuits micro welded to your ecu, im not exacly sure but i had to have mine sent to someone...

This weekend my buddys are going to help me disect this problem, im hopefull that i will, either come out with more usfull info, or have this problem fixed...

okay, this weekend was a great success... my detonatoin is fixed,

Here were the steps that fixed it...

1: Loose distributor rotor screw. Yup. Mista Bone gets a cookie. Replace rotor, add new screw WITHOUT stripped threads.

2: Timing belt had 20 mm play on the long side, 10 mm play on the W/P side. POSSIBLY more if I would have played with it, but the crank turned at LEAST 4-5 degrees without moving the cam. Replace and tighten.

3: Engine Ground straps? Where? Add 2.

4: Fuel MAP? Back to baseline plus 2% fuel on boost.

5: Distributor bolts... All 3 loose, turn the dizzy by hand. Every time he hammered it, the dizzy advanced to full advance, every time he lifted, it shot back to full retard. Tighten, and set it.

6: Fuel pressure was WAY too high for the 440's and the rich MAP. Reset it to 38 psi and calibrate MAP accordingly.

7: Plugs were too hot. 1 step colder.

She picked up 2 psi of boost. Peaks at 9.5 psi now instead of the usual 7.5. I'm assuming the timing belt being THAT loose was retarding the cam so far the overlap was blowing the boost out the exhaust side.
