Ive been told MSD chipset in std ecu,dreamscience,bluefin & FRP flash on Tape ecu.The lastest Ive read is you can live map the std ecu on rolling road.
What I what to know is if this is correct,bearing in mind I'm asking 'cos I want to fit different cams,& need 7.8k to use fully.Im unsure as to the reliability of this info,'cos nobody would pay for the other stuff if you can just set up std ecu .If you can help its apprechiated,with so many conficting opinions Im seeing why so many just use the FRP cams & a flashed Tape ecu.

Phone up Dreamscience in Hull. Also speak to MSD in Blackpool

standard ECU can not be tuned

[Big Boy Al]

Surely it can how did ford do it with a standard ecu and make an frp map?? Must be a way of doing it surely with the right know how?.

[t783vkj]

I contacted Dreamscience a while ago,they said they can raise rev limiter & ensure the fueling doesn't lean out, they sell you one of their modules with maps preloaded(£550)or attend one of their dealers who'll flash a single map for £350.But I spoke with a member who tried several of their maps on here who gave up in the end 'cos it never ran right using their products,he used a flashed Tape instead.To be honest I was hoping to hear from someone 1st hand whos successfully raised the limit,companies all say theirs is the best option available.

[martinthrapston]

have you thought about going for an aftermarket ecu which can be moddified to suit what you want to do,you will only be able to map the standard ecu so far,altering fail safe limits,rev limited and torque limiter ..

I know you don't end up with a 7.8K limit.
But I was looking into Dreamscience or Superships for my FRP.
Someone in the business said to me on the side, not to bother.
They said the best MAP for a FRP was the standard one, it hadn't been bettered by either of the above.
That will give you a 7.5K limit, but you need a Tape ECU flashed with it.

There is some one breaking a FRP on EBay at the moment
You need a key with the unit to program the cars security.

7250 limit Graham not 7500 ;-)

[Turby]

Give each of the companies a ring and take them up on their offer of their product with a guarantee it will do what you want ie raise the rpm limit. My advice is to go for an aftermarket ECU and get an expert (with your chosen ECU) to map your engine fully.

My Mistake
The needle only goes to 7K anyway.

I wouldn't be asking these questions if I was going to use aftermarket ecu,I want a cheap route to a raised rev limit.Unfortunately I don't have cash to just cherry pick all the best bits ,I'm increasingly thinking a cam with less duration is the way to go,that'll peak inside the FRP limit.

[ScubaSteve]

why do you want a 7.8k rev limit, it wont be beneficial that will be way past the peak torque and HP

Not with a high lift / long duration cam it wouldn't.
I have used some stupidly high lift cams in Escorts.
Not at all suited for road use, and horrible to live with in the long term.
One would just misfire and stutter before 4K and then it just came alive up to 8200 RPM where max power was delivered.
145bhp from a 1660 Kent Xflow.
Made the engine very fragile though.
The best I have used for a Piper 285H2, max power at around 7K and very usable from low down.
Why do you want to go to 7.8K? Is that the cam you are looking at rating?

[t783vkj]

Shawspeed SS4's peak power@7.6k ish ,
Dogsbody;I ran A3 cam in my 1700x/f, (310degree).wasn't ideal with std bottom end,it all went belly-up in a big way,some times more is too much.
Yeah the 285 cam from piper was the other I was considering,slightly put off by the fact piper haven't answer a single enquiry,Newman cams are the other supplier I was looking at.Again it would be handy to hear from someone that'd used these profiles,that was why I was considering the SS4's ,on ZCOC a few have used with 155+ from a 4:2:1 manifold,cam & panel filter.That's where I read about the MSD chipset to raise limit,but that's in the ZS ecu,which is different to puma.

I had the Kent 244 Rally cam in my Xflow, but I had a steel bottom end and knightrided crank
I'm surprised at Piper, they use to be very good.
Give them a ring, they are Folkstone now.
Used to be on the outskirts of Ashford when I dealt with them years ago.

Wrong again graham ;-). On both my frp and track puma the needle goes past the 7 :-).

[Dogsbody]

I will just go a stand in the corner
Never really noticed the needle, when the rev limiter come in.
I'm off to work shortly, but will have a look on my way in.
I can only do it in 1st or 2nd due to speed limits

Just got back from a roll test whit a 1700 puma. Std ecu and then reprogram whit DS. Full mapping and now it got the samm as the beging, but a better flow from 0 to 7250 rpm. No limit at 1 and 2 gear.
135bhp and 170 Nm.

Next step.
SS4
Flowt head
Throttle Bodies from Toyota
and then new setup whit the DS.

"Full mapping and now it got the samm as the beging,"............ what does that mean?

[MPMotorsport]

We had 133 bhp and 162 nm before DS (and still limit in 1 and 2 gear) after DS-mapping on roll-test it got 135 bhp and 170 nm, but when we took off the limit in 1 and 2 gear then we got a "new car" the handling is much better. Its alive...

New max rpm 7250.

The puma 1700 is on needly MAX power whit std ecu setup.
(forgot, we didt put on a 4-2-1 Branch Exhaust Manifold)

So you just get higher rpm limit (7250 rpm) and you will get the limit on 1-2 gear off.
DS is a fine system, but you need more modifications to get more bhp/nm.

This test was NOT a standdart setup program from DS. We build a new program whit help from the newest setup from DS and when on roll-test whit so we cut build the program.
