All year i have been running in 3 rd gear with a SOHC 3.94 trans. 185 60 R14, I was pulling about 5100 rpm. Started year off top 3 fastest car and then mid season everyone caught up! Changes needed to be made.

First i bought a ECU from a DOHC manual to raise the rev limiter. I still had my 185 60 r14 tire. Only tried it one hot lap season and found that it was hitting the rev limiter all the way around the track.

I then purchased a ECU from Skyed. Put on a 195 70 R14 tire and hot lapped the other night. I am turning 6600 rpm and I am a second plus slower than i was at the first of the year. It seems to stop pulling at 6000 rpm of so than goes flat!!

Also, This is a 96 car with a 2000 block/head with all accessories swapped over!

Any ideas on what this thing is doing?

The level of cheating has increased, you need to port the head and install a better cam, raise compression ratio, bore out TB, AMM intake, etc.

2 1/4" exhaust and a Flowmaster NO GLASSPAK

Work on your driving technique and car setup, the biggest gains are in raising corner speed.

I agree totally! Cam, porting and ext. Winter is coming! lol

But it doesn't make since that it stops pulling a 6000 or so? I run with a guy that has a 2004 SOHC Manual, running in 2nd. He hits the limiter (6850) every lap and he is fast!

Everything I have read says i should pull up to 7200 or so! I may be wrong but it seems like the valves are floating! (which is kind of what Ricksneon was getting at)

I am 1 1/2 second faster running in 3rd gear. but very doggie coming of the corners.

The car felt great running in second gear coming of the corners, it felt like a rocket! BUT SLOW at the end of the straightaways!

Buddy also has this problem with his syked ecu. It goes pig rich around same rpms on his sohc.

DOHC calibrations usually run rich up top on a stock cam SOHC.

(note that this is a DOHC Mopar PCM)

So an afc would be a good idea

Interesting! I wouldn't of thought that the HP/torque wouldn't drop off that bad!



So without going crazy on a head rebuilt right now, it is what it is?

Adding a magnum or crane/comp cam or switching to a PCM calibrated for a stock SOHC cam would fix it.

Timing? AFR? Fuel pressure? Knock? If fuel pressure is steady, run the stock computer to see if it improves above 6K.

I had a similar issue on my 03 where it just fell on its face at 6K. went through the fuel system, logged AFR. Even thought valvefloat for a second. In the end I had just fat fingerd too much timing at 6K. An obvious sudden spike of additional timming. OOPS.

The ecu that I got from Skyed was the original ecu that I sent to him (sohc mtx) i guess need to confirm with him why programming he put into it?

and you tested fuel pressure?

A cheap way to log PCM parameters is to find/beg/borrow a Diablo Sport Predator (DSP) or Trinity (DST) even if you bought a "locked" one off of Craigslist you can to diagnostics and view the common ODB outputs. I dont recall if that includes timing Its been too long since ive had it on another car besides my NGC. That plus a wideband will tell you all kinds of information about what is going on.

Are you taking the corners a lot faster causing the car to push or slide?

No, actually all I was doing at hot laps was rolling threw the corners! I wasn't even pushing The car in the turns. I may of drove it harder (to see max rpm) but i just rolled threw! This practice session was mainly to check rpm, gear and tire size with my new ecu!

If you was just rolling through the corners to check rpm out then you was not driving it hard like normal. By not driving hard your lap times are going to be down from what you ran before. I would try to run it hard for several laps to see what you can do with the car.

I agree! But i wasn't rolling that much and when I did get back into it went flat about mid way down the front/back stretch! Not exactly sure but I think I was turning 5000 rpm or so threw the turns

The only real change you have done is the Ecu. The car should be much faster in 2nd gear do you have another stock dohc ecu to throw in it to see if it flat with it? Much easier to pull hard out of the corners with the higher rpms in 2nd. I run all of mine in 2nd and they pull like a truck

Yes, I do have another Dohc ecu. That's what I am going try tomorrow!
Actually I have never tried (for the most part) running in second! So this is all new to me and the car!

As someone stated in a earlier post I was running a Dohc ecu on a sohc motor (until I got the Skyed one)
I am not sure if it matters (from the dyno chart it does) but I need to find out how this ecu was tuned!

At least with putting the stock dohc ecu back on you will know if the ecu is causing you some trouble

You can put the sohc ecu back on but the whole purpose is to run the car in 2nd gear

Check vavle springs?

Check Fuel pressure? I use an adjustable FPR so I could tune WFO.

Install wide band so you know where you are at AFR wise.

I have not check fuel PSI yet! Everything is new, but stock (pump,regulator original injectors)
Do you think that the tuned ecu needs more psi?

I installed the Dohc mtx ecu! Going racing tonight! We will see!!

Thanks for everyone's help!

The stock fuel pressure should b more than enough to handle your set up

Ran the car last night with a the Dohc MTX Ecu! Everything that the tuned ecu did this ecu did also! The dyno chart is dead on IMO!!
Ended up going back to smaller tires and ran in 3rd!

Head is going to the machine shop Monday!! Lol
Thank agin for all the help!

Are you guys running second gear with a 3.55 or 3.94 ratio in the transmission.

Something is wrong somewhere running in 3rd shouldn't be faster than 2nd gear. I have used different ecu on sohc cars and 2nd always was faster for me

or if somewhere put a dohc tranny in the car it would have the 3.94 ratio, I'm only asking because i have both transmissions and trying to figure out which one to run whether i should keep the my 3.94 and run second gear or run the 3.55 with second gear?

I run the 3.55 in 2nd and like it. So with a 3.94 in 2nd will it work for your track? I know most people would b all over the rev limiter with the 3.94 in 2nd

originally, yes this car had a 3.55. I lost two features with the notorious popping out of 3rd gear issues and the bell housing was cracked. So thinking that 3rd gear is what I needed to run in (noticed I said thinking) I switch to a 3.94.

After running the car last weekend and doing some thinking I think I figured out the issue!!

in hot laps, I was able to 76 inch tire (from the 69 inch I was running on when in 3rd) I was pulling HARD down the straights and driving the car same as before the tire/ecu swap. I was still a 1 second slow! So I switched back to the 60 inch tire and qualified in 3rd. (last night of racing and its what I knew) I was 3/4 of a second slower then the car is capable of!!

Now comes the answer! We have been rained out 3 weeks in a row prier to last weeks race!!! I had tall spring in the RR that was making the car higher on the right. Tech told me to level the car out! I was just going to try and cut it and see what happens! Well I can tell you what happens! 3 weeks of rain outs and you forget what you did. Cutting the RR spring doesn't give much plant to the LF wheel. But what sucks is our season is over other then some RWYB shows!!

After doing research tho I do feel that a Magnum or crane 12 with springs would help out A LOT!! Maybe this winter!!

i have a complete 01 magnum top end on my car including the header of course it is hid by the factory exhaust covers, and it makes a huge difference in performance.

nope i am running a stock dohc bottom end for now over the winter i plan to refresh the bottom end and shave .030 off the head according to the guys on here i should be 10.5-1 or more compression this way on all stock parts.
