Great work! That X -chip dyno is NOT smooth. Confirms what I felt when testing it.

I have never liked the X chip, and have always felt that it had very abrupt power on/off.

The MTM and ABT graphs are incredibly similar to stock in terms of smootheness. This seems to support what those two chip makers contend. If I was to choose a chip based on just those charts it would have to be ABT or MTM with the slight advantage to ABT because of the increased HP and Torque.

APR looks like it has some work to do.

Unfortunately that is a misrepresentation to get you to spend big bucks, it's AMS not ABT software - Milpitas2.7T 2003-03-26 15:18:52 (1684 views)

Yes, but it's still the best software on the market ;) - Argeiphontes 2003-03-26 18:32:54 (1171 views)

You would have to quantify that statement. - Milpitas2.7T 2003-03-26 19:40:19 (1122 views)

Tory, that's not really fair. I'm not disagreeing with you, but by that logic, MTM isn't MTM - 2k2S4 2003-03-26 16:44:48 (1311 views)

Actually no, here;'s why.. - Milpitas2.7T 2003-03-26 19:37:42 (1326 views)

Not true...MTM has sent engineers here. - RichP 2003-03-27 06:30:58 (1071 views)

True, but that still doesn't change the fact that Hoppen is an MTM reseller. - NonBenz OZ SL GB 2003-03-27 06:58:42 (790 views)

How can ABT make less torque, but 30 HP more at 500 rpm less than APR? Confusing. - PhoenixS4 2003-03-26 13:44:23 (1035 views)

APR's tuning on the M-box is either tuned very conservative or they have something wrong with the - The R 2003-03-26 17:05:01 (4019 views)

P.S. Confirms that short shifting is the way to go. - PhoenixS4 2003-03-26 13:51:14 (778 views)

Not if the final output torque with tranny gearing is still higher. (Which it probably is.) - BryanGT 2003-03-26 16:57:31 (612 views)

It matters where in the rev range you make that torque. HP = (torque x RPM)/5252. - 2k2S4 2003-03-26 13:51:07 (626 views)

Well the peak torque was at the same rpm, but I guess the APR tq curve falls off faster. - PhoenixS4 2003-03-26 13:53:12 (747 views)

Many Thanks. Great Work. I Love my X Chip!!!!!!! - S4SPEED-VA 2003-03-26 13:11:32 (977 views)

do they still have the data - can they plot APR vs MTM - that looks interesting - Mark P 2003-03-26 13:01:06 (733 views)

I can ask Todd, or Todd can you do it and post it here ? - xccess 2003-03-26 13:02:56 (671 views)

APR v3.3? I've seen a 2000 A-box v3.3 dyno 23hp/27lb-ft more than a 2001.5 M-box v3.2 - Third ROC 2003-03-26 12:40:30 (817 views)

Yes, v3.3.. - LightWeight 2003-03-26 12:48:42 (640 views)

That same 2000 APR A-box was 8hp less but 2 lb-ft more than a 2001.5 M-box GIAC X chip. - Third ROC 2003-03-26 12:46:31 (713 views)

Not really comparable, it depends on too many factors, the dyno itself being one of them. - 2k2S4 2003-03-26 12:46:03 (515 views)

The cars I'm talking about were on the same dyno. The v3.2 runs were from several 2001+ cars. - Third ROC 2003-03-26 12:48:51 (616 views)

Manifold pressure Vs. RPM, and the dyno's wideband O2 vs. RPM... - BryanGT 2003-03-26 12:47:22 (862 views)

003 (airflow and timing) for sure, maybe 115 (boost), 002 (air and fuel) - DarinS4Turbo 2003-03-26 12:46:43 (665 views)

I assume we can do all three block at the same time right ? - xccess 2003-03-26 12:51:48 (542 views)

Like Bryan said wideband is best, then just do 115 (manifold pressure) and 003 (timing/air) - DarinS4Turbo 2003-03-26 13:17:25 (553 views)

Yes, but you'll only get 1 sample per second that way. Do them seperately for a better sample rate. - 2k2S4 2003-03-26 12:55:29 (605 views)

Air fuel is more accurate when read externally (Wideband); you should be able to read 2 blocks... - BryanGT 2003-03-26 12:55:17 (546 views)

How's this for a thought: - 2k2S4 2003-03-26 12:01:40 (1042 views)

Agreed... - Milpitas2.7T 2003-03-26 12:42:50 (685 views)

I'm guessing every one of those chips boosts above 1.2 bar. 1.3 peaks seem to be par for the course. - 2k2S4 2003-03-26 12:09:54 (574 views)

yes 1.2+ bar at that rpm is within spec as per the compressor maps! - SlvrBulletS4 2003-03-26 12:06:28 (681 views)

Ok, well in my humble opinion the X-chip is still unrefined... - s4IRIsH 2003-03-26 12:18:59 (639 views)
